Answer:
Angle 5 = 35 degrees
Step-by-step explanation:
A straight line is equal to 180 degrees, meaning 1 + 2 + 5 = 180 degrees because they make up a straight line.
Angle 2 = 55 degrees
Angle 1 = 90 degrees (because it is a right angle)
Angle 5 = ?
Set up an equation:
90 + 55 + angle 5 = 180
145 + angle 5 = 180
Angle 5 = 35
Answer:
m<1 = 130°
m<2 = 50°
Step-by-step explanation:
Since given that line a is parallel to line b, and <1 and 130° are interior angles that alternate each other, therefore:
m<1 = 130° (alternate interior angle theorem)
Also,
130° and <2 lie on same side inside the parallel lines cut across by the transversal, therefore,
m<2 + 130° = 180° (same side interior angles theorem)
m<2 = 180° - 130°
m<2 = 50°
