Answer:
Step-by-step explanation:
-x + 2 = 3x + 6
3x + 6 = -x + 2
4x + 6 = 2
4x = -4
x = -1
y = 1 + 2 = 3
(-1, 3)
Answer:
B
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos30° = , then
cos30° = = = ( cross- multiply )
2x = 20 ( divide both sides by 2 )
x = 10 → B
