Solve for X, and show the equation you would use to solve.
2 answers:
Opposite interior angles are equal, so
4x - 10 = 2x + 20
2x - 10 = 20
2x = 30
x = 15
Answer:
4x-10=2x+20(being alternate angle)
or,4x-2x=20+10
or,2x=30
or,x=30/2
or,x=15
again,
4x-10 (putting the value of x)
=4×15-10
=60+10
=70
2x+20 (putting the value of x)
=2×15+20
=30+20
=50
