Answer:

  • x = 25
  • y = 16.3°
  • z = 73.7°

Explanation:

The length of the hypotenuse can be found using the Pythagorean theorem:

x² = 7² +24² = 49 +576 = 625

x = √625 = 25

__

The angles can be found from the sine relation.

Sin = Opposite/Hypotenuse

sin(y) = 7/25

y = arcsin(7/25) ≈ 16.3°

The acute angles in a right triangle are complementary, so ...

z = 90° -16.3° = 73.7°

Determine the unknown measures of the triangle shown. Round to the nearest tenth, if-example-1
