Answer:
C. m < A = 152.5 degrees.
Step-by-step explanation:
Use the Cosine Rule:
a^2 = b^2 + c^2 - 2.b.c.cos A
34^2 = 18^2 + 17^2 - 2.18.17 cos A
2.18.17 cos A = 18^2 + 17^2 - 34^2
cos A = (18^2 + 17^2 - 34^2) / (2.18.17)
cos A = -0.88725
m < A = 152.5 degrees.

Answer:
x = 100
Step-by-step explanation:
1. To get rid of the denominator of 5, multiply both sides of the equation to get 5
-40 + x = 60
2. Add 40 on both sides to get the variable x by itself
x = 60 + 40
3. Solve
x = 100
