Question

What is the value of x? a. 68° b. 62° c. 112° d. 124°

Answer 1

68 degrees because 56×2=112 then 180-112=68

Answer 2

The sum of all angles of a triangle is equal to 180°

On a isosceles triangle, the base angles are the same. 

We add them together 56° + 56° = 112°

To know X, we subtract 112° from the total

180° - 112° = 68°

X = 68°

OR as an equation

56 + 56 + x = 180
112 + x = 180
x = 180 - 112
x = 68
