Question

i need help with my math questions

Answer 1

Answer: 37°

Step-by-step explanation:

Opposite angles are equal when two lines cut or intersect each other.

Therefore we can say that 74°=2x°

x=74/2=37°

Answer of next question is Supplementary , 19

Supplementary angles form 180 degree angle and a straight line has 180 degree angle on it.

123+3x=180

3x=57

x=19

Answer 2

• 2x=74° ( v.o.a)

X=74/2

X=37°

• 123°+3x=180°{supplementary angles}

3x=180-123

3x=57

X=57/3

X=19°
