Here are the answers:
1) C
2) A
3) D
4) B
We know by definition that complementary angles add up to 90 degrees. We can set up an equation using the ration given:
17x+13x=90, with x representing the amount you need to multiply the ratio by to get 90.
17x+13x=90
30x=90
x=3
We now know that the number we multiply the ratio by is 3. The smaller number in the ratio is 13, and so therefore we multiply it by 3.
3*13=39
The answer is 39 degrees.
(7 + i) - (6 - 2i) = 7 + i - 6 + 2i = 1 + 3i
X=2 and you go up on the y-intercept 2 times and move 1 right.
