Question

In AJKL, m/J = (8x - 7)°, m/K = (x + 7)°, and m/L= (2x + 15)°. What

is the value of x?

PLS HURRY

Answer 1

x = 15

Explanation:

The sum of interior angles in a triangle is equal to 180°.

m∠J + m∠K + m∠L = 180

• Write this with the given measures.

8x - 7 + x + 7 + 2x + 15 = 180

• Add like terms.

11x + 15 = 180

• Subtract 15 from both sides.

11x = 165

• Divide both sides by 11

x = 15
