Question

In the diagram m<4 is (7x+7),m<2 is (4x+4), and <3 is (4x ? 9). what are m<4 and m<1

Answer 1

Explanation:

7x-11=4x+4(being vertically opposite angles)

7x-4x=4+11

3x=15

x=15/3

x=5

angle 2+angle1=180 degree(being straight line)

7x-11+angle 1=180

7*5-11+angle 1=180

35-11+angle1=180

24+angle 1=180

angle 1=180-24

angle 1=156 degree
