Suppose the following triangle is isosceles. Find the value of x.

x = 62

Step-by-step explanation:

Because of the given congruent sides, the base angles both measure x.

x + x + 56 = 180

2x = 124

x = 62

if the triangle is an isosceles triangle then x is equal to the other angle that is unknown. So

180-56=124. Since there are still 2 angles left you divide 124/2=62

x=62

43

step-by-step explanation:

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
