Answer:
x +(2x + 3) = 33
Step-by-step explanation:
two equations can be derived from the question
c = 3 + 2x equation 1
c + x = 33 equation 2
where :
c = cappuccinos
x = lattes
make c the subject of the formula in equation 2
c = 33 - x equation 3
equate 3 and 1
x +(2x + 3) = 33
6.2^2 + b^2 = 8.7^2
38.44 + b^2 = 75.69
b^2 = 37.25
b ≈ 6.1
Sinx=0.9
arcsin0.9=x
cos(arcsin0.9)=0.436
Answer:
x is three the ratio show you what you need to divide by so triangle a is 3 and triangle b is 8 times larger than triangle a.
