1.The vertex angle of an isosceles triangle is 57° 24’ and each of its equal sides is 375.5 ft. long.Find the altitude of the triangle.

2.Solve the following right triangles:
a. a=117 ft.--B=16.35ft.
b. B=8°29, --a=32.8 ft.

Answer 1

1. So, you have two sides and included angle. Find the 3rd side and either use Pythagorean theorem to calculate the altitude or use the tangent of 1/2 the angle and 1/2 the base.

2a. You have two sides and the included angle
2b. You have two angles and the included side
