Question

what is the value of t? 43° identify complementary, supplementary, vertical, adjace... (28) angle measures lesson: supplementary angles

Explanation:

Step1: Recall supplementary - angle property

Supplementary angles add up to 180°.

Step2: Set up equation

Let the given angle be 43°. We have the equation \(t + 43^{\circ}=180^{\circ}\).

Step3: Solve for \(t\)

Subtract 43° from both sides: \(t=180^{\circ}- 43^{\circ}\).
\(t = 137^{\circ}\)

Answer:

137
