Complementary angels add up to 90°
so x+18°=90°
so x=90-18=72°
Answer:
77.41
Step-by-step explanation:
4.6² + 7.5²= 77.41
Square root of 77.41:
√77.41
This is because it can not be simplified further!
Why?
Because we used the Pythagoras Formula which is a²+ b² = c².
This is also why we had to find the square root of 77.41.
Well, both sides are equal to 1, so I'm thinking "="
7x+2(5x)=-17
7x+10x=-17
17x=-17
x=-1
y=5x=5(-1)=-5
