Answer:
x = 16
Step-by-step explanation:
The triangle in question is an isosceles triangle which means :
m<Q = m<P and the sum of interior angles in a triangle is equal to 180
so we can find the value of x using the following equation:
5x - 2 + 3x + 3 + 3x + 3 = 180 add like terms
11x + 4 = 180 subtract 4 from both sides
11x = 176 divide both sides by 11
x = 16
