Question

If three angles (3x-7)°, 55°, (x+20°) makes a linear pair then find x.

Answer 1

Answer:

(3x-7)+55+x+20=180

3x+x=180-55-20+7

4x=120

x=30

3x-7=83

x+20=50

Answer 2

Answer:

28 degree

Step-by-step explanation:

3x-7+55+x+20=180 degree

4x+68=180 degree

4x= (180-68) degree

4x=112 degree

x= 112/4

x=28 degree
