If two lines intersect, they intersect at two different points.
is this statement true or false
Answer: False
If two lines intersect, then they intersect at one point only, so it makes no sense to mention a second point. This is assuming that we're not talking about two lines intersecting infinitely many times (i.e. one line overlapping another perfectly).

Find type of angle and solve for x.Please help.
Step-by-step explanation:
72° and a° is the angle of a straight line so
a+72°=180
a=180-72
a=108°
By using alternate exterior angle definition:
7x+24=180
7x=108-24
7x=84
x=84/7
x=12
there are 78.1 grams of carbon in a sample of 92.7 grams of octane. what is the percent of carbon within the sample of octane?
The percent of carbon within the sample of octane is 84.25%
A percentage is a fraction of a total amount divided into hundred parts
The percent of carbon within the sample of octane = (grams of carbon / grams of octane) x 100
(78.1 g / 92.7 g) x 100 = 84.25%

The percent of carbon within the sample of octane in the exercise is:
84.25%Calculation of percentages using the rule of three.
To make a calculation of the percentage of a sample, a simple rule of three can be used, where it is identified:
92.7 g → 100% 78.1 g → x
The octane sample is used as 100% since it is the total sample, while carbon is only a part of it, now we proceed to calculate:
[tex]x=\frac{78.1*100}{92.7}[/tex][tex]x=\frac{7810}{92.7}[/tex]x = 84.25026969x ≅ 84.25%In this way, it can be identified that the percentage of carbon in the octane sample is approximately 84.25%.

What would the sum of the interior angles of a 14 sided shape be?
Select one:
O a. 360°
O b. 180°
O c. 14°
O d. 2,160°
Answer:
the sum of interior angles of a 14 sided shape be 2160
Answer: D) 2160
Work Shown:
S = sum of the interior angles of a polygon with n sides
S = 180(n-2)
S = 180(14-2)
S = 180*12
S = 2160

a. Find the value of sin2A, cos2A, tan2A and cot2A when sinA = 4/5 , cosA =4/5, tanA= 3/4 and cotA = 12/13
Step-by-step explanation:
Given,
SinA = 4/5
CosA =4/5
TanA= 3/4
CotA = 12/13
Sin²A = SinA²
Cos²A = CosA²
Tan²A = TanA²
Cot²A = CotA²
Therefore,
Sin²A = (4/5)²
Cos²A = (4/5)²
Tan²A = (3/4)²
Cot²A = (12/13)²
Sin²A = 16/25
Cos²A = 16/25
Tan²A = 9/16
Cot²A = 144/169
