f < A and < B are complementary, and < A = 3x + 4 degrees, while < B = 6x - 4 degrees, find x.
1 answer:
Answer:
x = 8/3 or 2 2/3
Step-by-step explanation:
if angles A and B are complementary then their sum is 90 degrees
we can write the following equation to find 'x':
3x + 4 = 6x - 4
subtract '3x' from each side:
4 = 3x - 4
add 4 to each side:
8 = 3x
divide each side by 3:
8/3 = x
or x = 2 2/3
