Question

Find the value of X PLEASEEE

Answer 1

51

Explanation:

All angles add up to 180. The straight line on the bottom is 180 degrees so 180-117 to find that angle. which equals 63. Then add 63 plus 66 (the other angle) which equals 129. Since they all have to equal 180, subtract 180-129 which equals 51 :)

Answer 2

51 degrees

Explanation:

x + 63 + 66 = 180

x + 129 = 180

x = 51

you get 63 by subtracting 117 from 180; those 2 angles form a linear pair
