Answer:
ty = 53
Step-by-step explanation:
Given
= 
Cancel the z on the numerator/denominator of the left side and
Cancel the w on the numerator/denominator of the right side, leaving
= 
Cross- multiply
ty = tx ← tx = 53, hence
ty = 53
The proper equation used to solve this is (let's use E for edge) E=V^1/3
The V stands for volume. So, your equation is 512^1/3
Your answer is 8, which is what you get when you work this out.

Answer:
17) x = 10√2
18) x = 4√6
Step-by-step explanation:
These problems rely on your knowledge of the side ratios of special triangles
45°-45°-90° triangle: 1 : 1 : √2
30°-60°-90° triangle: 1 : √3 : 2
__
17) 5 is the short side of the isosceles right triangle, so its hypotenuse is 5√2. That length is the shortest side of the 30/60/90 triangle, so its longest side is 2 times that:
x = 10√2
__
18) 8 is the longest side of the 30/60/90 triangle, so its long leg will be 8(√3)/2 = 4√3. The hypotenuse of the isosceles right triangle is √2 times that, so ...
x = (4√3)(√2)
x = 4√6
