Please help!! List the sides of ∆XYZ in order from shortest to longest if m∠X = 51, m∠Y = 59, and m∠Z = 70.

x = 10

Step-by-step explanation:

Since this is an isosceles triangle: 2 sides will be equal.

There is enough information to use the Pythagorean Theorem to solve for x.

1. Make a right triangle with an altitude of 8 and a leg of 6 that will be perpendicular to each other.

2. Then use the Pythagorean Theorem formula:

8^2 = 64

6^2 = 36

64 + 36 = 100

Take the square root of 100

= 10

x (the hypotenuse) = 10
