Answer:
1. (5x - 2) + (2x - 2) + x =
2. m<J =
3. m<K =
4. m<L =
Step-by-step explanation:
Generally, the sum of angles in a triangle = .
So that;
m<J + m<K + m<L =
(5x - 2) + (2x - 2) + x =
5x + 2x + x -2 -2 =
8x - 4 =
8x = + 4
8x = 184
x =
x =
Thus,
m<J = (5x - 2)
= 5(23) - 2
=
m<K = (2x -2)
= 2(23) - 2
=
m<L = x
=
