I believe the answer to your question would be x = -y + 2
The answer would be 20 degrees.
2*20
3*20
4*20
All triangles must three degrees that equals 180.
Answer:
BC = BA
Step-by-step explanation:
Answer:
x = 18.
Step-by-step explanation:
The 2 amgles are adjacent so add up to 180 degrees so we have:
x^2 - 11x + 3x = 180
x^2 - 8x - 180 = 0
(x -18)(x + 10) = 0
x = -10, 18.
x = -10 cannot be correct because that would make the 3x angle = -30.
