Cos(30)=x/20(squarerootof)3 (lolz, sorry bout that xd)
x= 30
sin(30)=y/20(squarerootof)3
y=17.32
you'll have to change Y into a fraction or square root I think...
but yee
Answer:
D. 60
Step-by-step explanation:
4(3x + 3) = 5(x + 8) 12(4) + 12 5(4) + 40
12x + 12 = 5x + 40 48 + 12 20 + 40
-5x -5x 60 60
7x + 12 = 40
-12 -12
7x = 28
x = 4
Multiply 3.6666 by 3.25 to get 11.9167 cups.
Answer:
51
Step-by-step explanation:
trapezoid area calculator, A=(a+b/2)h
Y = -(1/2)x + 4
y + (1/2)x =4
(1/2)x + y = 4
Multiply both sides by 2
2*(1/2)x + 2*y = 2*4
x + 2y = 8
Option B.
