Answer:
18,72
Step-by-step explanation:
Complementary angles add to 90 degrees
Multiply the ratio by x
1x+4x = 90
Combine like terms
5x = 90
divide by 5
5x/5 = 90/5
x =18
The first angle is 18 degrees
4*18 =72
The second angle is 72 degrees
Answer:
The awnser is 7/4!!!!!!!!
Answer: 5 and 4
Step-by-step explanation:
Perimeter = 2 ( L + W)
18 = 2(L + W) divide through by 2
9 = L + W
9 - L = W
Area = L * W
20 = L (9 - L)
20 = 9L - L^2
L^2 - 9L + 20 = 0 factor
(L - 5) (L - 4) = 0
Set both factors to 0 and solve for L
L = 5 and L = 4
