Given:
If two angles are vertical and one of the angles is 2x+10 and the other is 70 degrees.
To find out:
Find the value of x ?
Solution:
2x + 10 = 70° [ Given ]
=> 2x = 70 - 10
=> 2x = 60
=> x = 60/2
=> x = 30°
Hence, the value of x is 30°
Answer:
x = 30
Explanation:
Vertical angles have equal measures, so ...
2x +10 = 70
2x = 60 . . . . . . subtract 10
x = 30 . . . . . . . divide by 2
