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:
67.5
Step-by-step explanation:
Well area of a triange is 1/2bh so we can find the side closest to us by doing
1/2(3x4) which is 12
the other side would be 1/2 (3x5) which is 7.5
the bottom side would be 1/2(8x4) so 16
and 1/2 (3x8) so 12
1/2 (8x5) so 20
add those together to get 67.5
Hope this helped ya!
Answer:
(y-12)/4
Step-by-step explanation:
If g(x) is the inverse of f(x)
and f(x) = 4x + 12
f⁻¹(x) = g(x)
let f(x) be represented as y
f(x)
= y
y = 4x + 12
subtract 12 from both sides
y-12= 4x
divide both sides by 4
(y-12)/4 = x
so f ⁻¹ (y)= (y-12)/4 so g(x) = (x-12)/4
Answer:
22½ in³ or 22.5 in³
Step-by-step explanation:
V=bwh
V=5(3)(1.5)
V=15(1.5)
V=22.5
