Answer:
Explanation:
The first triangle right isosceles. The sides opposite the 45° angles are the same length.
x = 13
By the Pythagorean Theorem, y = 13√2
:::::
Second triangle is 30°-60°-90°. Remember that the sides of a 30°-60°-90° triangle are in the ratio 1:√3:2.
The side opposite the 30° has length 3, so the side opposite the 60° angle is 3√3 and the side opposite the 90° angle is 6.
x = 6
y = 3√3
:::::
The third figure has another 30°-60°-90° triangle. The side opposite the 30° angle is 17, so the side opposite the 60° angle is 17√3 and the side opposite the 90° angle is 2×17 = 34.
x = 17√3
The other triangle is right isosceles.
z = 34
y = 34√2
