The value of angle a is 48° and angle b is 65°.
What is angle?
An angle is the formed when two straight lines meet at one point, it is denoted by θ.
Solve for the angle a,
Given that the lines are perpendicular to each other,
Implies that,
a+42=90
a=48
The value of angle a is 48°.
Solve for angle b,
The angle made by a straight line is 180°
therefore,
115+b=180
b=65
The value of angle b is 65°.
