Hope this help you with this problem!
Answer:
Step-by-step explanation:
<u>Formulas used:</u>
- sin θ = sin (180 - θ)
- sin θ = opposite/hypotenuse
<u>Opposite:</u>
- y- coordinate of given point = 21
<u>Hypotenuse:</u>
- √x²+y² = √20²+21²= √841 = 29
<u>Then</u>
Correct choice is D
Answer:
a) 
b) y
Step-by-step explanation:
Plug in the values into the compound interest formula
Step-by-step explanation:
(3x-11)+(2x+11)+2y = 180
5x+2y = 180
(3x-11)+(2x+11)=2y
5x = 2y
x = 18
y = 45
