Question

if angle 6 is 25 degrees, how many degrees is angle 7? 90 degrees 50 degrees 25 degrees 155 degrees

Explanation:

Step1: Identify angle - relationship

Angle 6 and angle 7 are supplementary (linear - pair of angles). The sum of angles in a linear pair is 180 degrees.

Step2: Calculate angle 7

Let the measure of angle 7 be \(x\). We know that \(\angle6 + x=180^{\circ}\). Given \(\angle6 = 25^{\circ}\), then \(x = 180^{\circ}-\angle6\).
Substitute \(\angle6 = 25^{\circ}\) into the formula: \(x=180 - 25\).
\(x = 155^{\circ}\)

Answer:

155 degrees
