Answer:
99 degrees
Step-by-step explanation:
81+a=180, so
180-81=99
a=99
Answer:
54 degrees
Step-by-step explanation:
Complementary angles add to 90 degrees
3:2
Multiply each by x
3x:2x
Add the angles together and set equal to 90
3x+2x = 90
Combine like terms
5x= 90
Divide each side by 5
5x/5 = 90/x
x =18
The angles are 3x = 3(18) =54
and 2x = 2(18) = 36
Area of Trapezoid = h(b1+b2/2)
b1 and b2 are the lengths of each base and h is the height.
Area = 16(20+24/2)=352 Square Feet
352/20=17.6 Cans of paint.
Hope this helps and is correct, I haven't done this kind of math in a while.
False. For every x in the function's domain, f(x) describes the one single output.
