To answer this, we're going to have to use cosine (adjacent:hypotenuse)
cos42 = x/15
You'll need a list or a calculator to find cos42:
-0.39998531498 = x/15
We should round to the nearest ten thousandth:
-0.4 = x/15
x = -6
Answer:
volume of cone=1/3 πr²h=1/3 ×22/7×6×12=24cm²
B)tan A=7/24. Because it’s the only correct ratio. Tan=opp/adj. Others are not the correct ratios so they can’t be used.
Answer:
you will have enough money though
Step-by-step explanation:
Value + value = 14 dollars
0.65x + 10-0.40x = 14
0.25x = 4
x = 16
25-x =9
