Question

The sum of the angles of a triangle is 180°.

a. Write a number sentence to represent the situation pictured at the right.

b. Find m2C and mA.

Answer 1

Explanation:

a. the triangle situation can be represented by the equation 3x + 30 = 180

b.

m<C

3x + 30 = 180

3x = 150

x = 50

m<C = 50

m<A = 2(50)

m<A = 100
