The figure shows two angles. What is the value of x?

Answer:
x=70
Step-by-step explanation:
First subtract 30 from 180
180-30=150
Subtract 10 from 150
150-10=140
Divide 140 and 2
140÷2=70
Answer:
x=70
Step-by-step explanation:
angles on a straight line add to 180
so first you do 180-30 which equals to 150
this means that 2x+10=150
take away 10 from both sides and your left with
2x=140
since you are finding x
you divide both sides by 2
x=70
