Answer:
w = 10√2
y = 20
Step-by-step explanation:
Sum of interior angles of a triangle = 180°
Therefore, the triangle on the left (with side length 10) is a right triangle,
since 180° - 45°- 45° = 90°
As this triangle is also an isosceles triangle (since it has 2 equal angles), then it will have 2 sides of the same length.
So the legs of the right triangle are both 10 units.
Using Pythagoras' Theorem to calculate the hypotenuse of this triangle:
⇒ 10² + 10² = c²
⇒ 200 = c²
⇒ c = √200
⇒ c = 10√2
The triangle with side w and base y is also isosceles triangle with base angles of 45°.
Therefore, the sides are equal in length.
So w = hypotenuse of the left triangle = 10√2
We know that the horizontal distance between the left base vertex and the top vertex of this triangle is 10, therefore y = 10 + 10 = 20

Answer:
Volume of the cylinder is 87.9 cm³Step-by-step explanation:
Given that Radius of the cylinder is 2 cm and height is 7 cm. To find Volume of the Cylinder we will substitute the value of height and radius in given formula:
[tex] \\ \: \: \dashrightarrow \: \: { \underline{ \boxed { \pink{ \pmb{ \mathfrak{ Volume_{(Cylinder)} = \pi r^2h}}}}}} \\ \\ [/tex]
Substituting the required values:
[tex] \\ \: \: \dashrightarrow \sf \: \: Volume = 3.14 \times {(2)}^{2} \times 7 \\ \\ [/tex]
[tex]\: \: \dashrightarrow \sf \: \: Volume = 3.14 \times 4 \times 7 \\ \\ [/tex]
[tex]\: \: \dashrightarrow \sf \: \: Volume = 3.14 \times 28 \\ \\ [/tex]
[tex]\: \: \dashrightarrow \: \: { \underline{ \boxed { \pink{ \pmb{ \mathfrak{ Volume = 87.9 \: {cm}^{3}}}}}}} \\ \\ [/tex]
Hence,
Volume of the cylinder is 87.9 cm³Step-by-step explanation:

Kira’s office has two printers. The printing rate of printer 1 is shown in the table. The printing rate of printer 2 is shown in the graph
Indicate which proportional relationship, and explain how the other printer needs to change to become proportional.
Answers
The number of pages prints at t=4 minutes is P1=64 pages.
The first coordinate of the graph is (a, b)=(0, 0).
The second coordinate of the graph is (c, d)=(10 min, 250 pages). The expression for the rate of the pages printed by the first printer is,
r1 = p1 - p0 / 4-0
Substitute the given values in the above expression.
r1 = 64 pages - 0 / 4 minutes - 0
= 16 pages / min
b) Printer 1 prints at an exponential rate. Both the x and y values increase by a constant ratio of 2. We can either use a logarithm of the first printer or find a constant number of documents it can print / time to become proportional.

For triangle xyz , the measures of angles x,y, and Z are known. Which method should be used to start solving triangle xyz?
law of sines
law of cosines
neither law can be used
both laws can be used
Answers
The triangle xyz has three sides and three angles
Neither law can be used to solve the triangle
How to determine the appropriate method?As a general rule, the law of sines states that:
x/sin(X) = y/sin(Y) = z/sin(Z)
As a general rule, the law of cosines states that:
x^2 = y^2 + z^2 - 2yz cos(X)
From the question, we understand that only the angle measures are given.
The sine and the cosine laws above require at least one side length of the triangle in order to solve the triangle
Since the side lengths are not known, then neither of the laws can be used
