Each base angle is an isosceles triangle measures 55 degrees 30 minutes. each of the congruent sides is 10 centimeters long. estimate the following problems to the nearest tenth. a. find the altitude of the triangle. b. what is the length of the base? c. fund the area of the triangle.

To solve the problwm we must know about trignometric functions.

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.

The area of the triangle is 46.672 cm².

Given to us

Assumption

Let the altitude(QS) be h, and the base of the triangle(PR) be b.

A.)   The altitude of the triangle

In ΔPQS

Hence, the altitude of the isosceles triangle is 8.24 cm.

B.)  The length of the base

In ΔPQS

Hence, the base of the isosceles triangle is 11.33 cm.

C.) The area of the triangle

Hence, the area of the triangle is 46.672 cm².
