Find the measure of each marked angle.
Top left angle measure:
___ degrees
Bottom right angle measure:
___ degrees
Please explain how

Answer 1

Answer:

60°,60°

Step-by-step explanation:

10x - 20= 7x + 4 (alternate exterior angles)

10x-7x = 4+20

3x = 24

x = 24/3

x=8

top left angle measure = 10x-20

= 10(8) - 20[substitute 8 for x]

80-20

60°

bottom right angle measure = 7x+4

=7(8) +4[substitute 8 for x]

56+4

60°
