Question

HELP 10PTS!! what is the value of x?

Answer 1

this is an Isoseles triangle. this means that the angle that isn't labeled will also be 56. Since all angles of a triangle add up to 180, you add all the angles together and get 180 = 56 + 56 + x.
add like terms: 180 = 112 + x. subtract 112 from both sides: 68 = x. and that's your answer.

Answer 2

68

Explanation:

Since this is an isosceles triangle the bottom 2 angles are equal. So both bottom angles are 56 degrees. The three angles of a triangle add to 180 degrees.

56+ 56+ x = 180

Combine like terms

112 +x =180

Subtract 112 from each side

112-112+x = 180-112

x =68
