Question

use the relationship between the angles in the figure to answer the question. which equation can be used to find the value of x? x + 90 = 61 x + 90 + 61 = 180 x + 61 + 90 = 90 x + 61 = 180

Explanation:

Step1: Identify angle sum rule

The three angles (61°, 90°, \(x^\circ\)) form a straight line, so their sum is 180°.

Step2: Form the equation

Combine the angles into a sum equal to 180.
$$x + 90 + 61 = 180$$

Answer:

x + 90 + 61 = 180
