Suppose c = 5 and A = 85 degrees.
Answers
Answer:
a = 4.98
b = 0.44
B = 5
Concept:
Here, we need to know the idea of the Pythagorean theorem and basic trigonometry ratios.
Pythagorean theorem: a² + b² = c²
a = legb = legc = hypotenuseTrigonometry ratios:
Sine = Opposite / Hypotenuse = O/HCosine = Adjacent / Hypotenuse = A/HTangent = Opposite / Adjacent = O/ASolve:
**Disclaimer** The question did not clarify which place did it required to be rounded to as some of the values are infinite. I rounded to the hundredth place. If it is fine, then you may refer to my answers. If it is not, then you may tell me and I'll redo it.
Given information
c = 5
A = 85°
PART ONE: Find the value of [a]
sin (A) = Opposite / Hypotenuse = a / c
sin (85) = a / 5
a = 5 · sin (85)
a = 4.98
PART TWO: Find the value of [b]
cos (A) = Adjacent / Hypotenuse = b / c
cos (85) = b / 5
b = 5 · cos (85)
b = 0.44
PART THREE: Find the value of [B]
Since the triangle as a right angle sign, meaning it is a right triangle.
Therefore, the corner angle is 90°.
90 - 85 = 5°
Hope this helps!! :)

using the variable n write an algebraic expression for a number increased by 6
Answers
The answer you are looking for is simply just n+6.
Solution/Explanation:
If you use the variable "n" to write an algebraic expression, for a number increased by 6, you must write it like this:
n+6.
And, also, increase obviously means the same thing as adding.
So, therefore, "n" stands for the number in this algebraic expression, and if you add 6 to that number "n," it must be n+6.
So, therefore, the final answer is n+6.
I hope that this has helped you. Enjoy your day, and take care!

When evaluating the value of an expression, we need to follow the order of operations which is PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction).
First, we will evaluate the exponent. 3² is 3×3 which is 9.
[tex]\frac{9+2*8}{16-11}[/tex]
Now we have to do multiplication. Since the multiplication sign is between the 2 and the 8, that is what we multiply.
[tex]\frac{9+16}{16-11}[/tex]
Then we will do our addition and subtraction.
[tex]\frac{25}{5}[/tex]
Since all fractions are just division problems, we can do 25÷5.
25÷5=5
So, the value of this expression is 5.

The area of a square is 16cm²
What is the perimeter?
Answers
Answer:
Perimeter = 16 cm
Step-by-step explanation:
The formula for a square's area = s^2 where the length of the side is s.
s^2 = 16 Take the square root of both sides
sqrt(s^2) = sqrt(16)
s = 4
The perimeter is the same
P = 4*s
P = 4 * 4
P = 16
Answer:
16
Step-by-step explanation:
Square root of 16 = 4cm
4 sides, 4 * 4 = 16cm
-21 - 8a = -5(a +6)
Step by step if possible
Answers
Answer:
Step-by-step explanation:
First multiply the -5 to (a+6)
The equation will look like this
-21 - 8a = -5a -30
then move the numbers around where you have a value times on one side, and a normal value on the other
add -5a to -8a, and add -21 to -30
the equation should look like this:
-13a = -51
then you need to get the a by itself, so divide -13 by -51
a= 13/51 (as a fraction with 13 on top)
a = 3
Step-by-step explanation:
-21 - 8a = -5(a + 6)
-21 - 8a = -5a - 30
8a + (-5a) = 30 - 21
3a = 9
a = 9/3
a = 3

The double bar graph shows how long, on average, different

Which animal's life span in captivity has the least difference from
its life span in the wild?
ears
Answers
Answer: Cheetah
Step-by-step explanation: I got it right on the test :)
The animal with the least difference is cheetah with a value of 5
From the double bar chart attached :
Life span in wild is = blue bar
Life span in wild is = blue bar Life span in captivity = brown bar
Calculating the approximate difference between the two bar values as obtained from the graph :
CHEETAH = 17 - 12 = 5
POLAR = 35 - 20 = 15
TIGER = 26 - 20 = 6
GIANT PANDA = 30 - 20 = 10
LEOPARD = 28 - 20
The animal with the least difference between it's span in the wild and in captivity is CHEETAH with a value of 5.

there are 14 math teachers and 26 science at school today what is the ratio of math teachers and science at school?
Answers
Answer:
Answer is 7:20
It's basically asking "what is the ratio of math teachers to total teachers?" assuming there are only math and science teachers at this school. For the sake of simplicity, let's just go with that. We have 14 math teachers and 14+26 = 40 teachers total. The ratio of math to total is 14:40 which reduces to 7:20 when we divide both parts of the ratio by the GCF 2.
Step-by-step explanation:
Answer:
the ratio is
14:26
but you can leave the answer like this the two numbers can be divided by 2 so
14/2=7 and 26/2=13
then the answer is 7:13.

So; X = 85° ; < PON(iV)
x + 47 + 75 = 180
x + 122 = 180
x = 180 – 120
x = 58
So; x = 58° ; < COB(Vi)105 ° = 3 x° –> Opposite angles ,
x = 105 / 3
x = 35
