Question

use your equation to solve for the value of a, or the measure of angle a. e = 35° d = 145°

Explanation:

Step1: Set up the equation

Since \(a\) and \(e = 35^{\circ}\) are complementary (they form a right - angle, \(90^{\circ}\)), the equation is \(a+35 = 90\).

Step2: Solve for \(a\)

Subtract \(35\) from both sides of the equation: \(a=90 - 35\).

Answer:

\(a = 55\)
