Question

in the figure below, what is the value of a?
135°
a°
a 35
b 45
c 90
d 135

Explanation:

Step1: Recall the property of supplementary angles

Supplementary angles add up to \(180^{\circ}\).

Step2: Set up the equation

\(a + 135^{\circ}=180^{\circ}\)

Step3: Solve for \(a\)

\(a = 180^{\circ}- 135^{\circ}\)
\(a = 45^{\circ}\)

Answer:

B. 45
