Answer:
The answer to your question is: B and D are correct
Step-by-step explanation:
Remember that the sum of the internal angles in a triangle equals 180°.
The sum of supplementary angles equals 180°
Then
(6x + 1) + (4x + 5) + [180 - (8x + 30)] = 180
6x + 1 + 4x + 5 + [180 - 8x - 30] = 180
10x + 6 + 150 - 8x = 180
2 x = 180 - 156
2x = 24
x = 24/2
x = 12
∠JKL = 4(12) + 5 = 48 + 5 = 53
∠KJL = 6(12) + 1 = 72 + 1 = 73
∠KLJ = 180 - 73 - 53 = 54
∠KLM = 126
