Question

In the figure, three line segments cross at a common point. Angle A is 45°, and angle E is 85°. What is the measurement of angle F?

A.40°
B.45°
C.50°
D.85°

Answer 1

C

Explanation:

We know a straight angle is 180 degrees ( a straight line).

Looking at the figure, we can say that A + F + E = 180 (since it creates a straight line).

We know A = 45, E = 85, plugging these into the equation, we can solve for F:

A + F + E = 180

45 + F + 85 = 180

130 + F = 180

F = 180 - 130

F = 50

Answer choice C is right.
