Answer:
- (4x -4)° +x° +(6x-3)° = 180°
- J = 99°
- K = 64°
- L = 17°
Explanation:
The relation that helps you write an equation for x is, "the sum of angles in a triangle is 180°."
__
equation
(4x -4)° +x° +(6x -3)° = 180° . . . . . sum of angles in this triangle
solution for x
11x -7 = 180 . . . . . . . divide by °, collect terms
11x = 187 . . . . . . . . add 7
x = 17 . . . . . . . . . divide by 11
angle values
m∠J = (6x -3)° = (6(17) -3)° = 99°
m∠K = (4x -4)° = (4(17) -4)° = 64°
m∠L = x° = 17°
