Answer:
54
Step-by-step explanation:
The two angles add to 90 degrees since they are complementary
the ratio is 3:2
Multiply by x
3x:2x
Add them together and set equal to 90
3x+2x=90
5x=90
Divide each side by 5
5x/5 = 90/5
x = 18
The first angle is 3*18 = 54
The second angle is 2*18 = 36

Garden
max area is if the sides are as equal as possible
so he should try to make a square (ideal is a circle, but barn walls are normally straight)
squaer perimiter=4 times legnth of 1 side
perimiter=amount of fencing=80
80=4s
divide 4
20=s
one sides=20
area=legnth times width
in squaer, legnth=width
20=legnth
20=width
area=20 times 20=400
dimetions are 20ft by 20ft to give 400ft^2
(fun fact, if it were a circle, the area would be about 509.5ft^2)
answer is 20ft by 20ft and area=400ft^2
Answer:
5x+8
Step-by-step explanation:
We have to distribute the + into -7x+5. So the equation will now be 12x+3-7x+5. Now let's organize it into terms. 12x-7x+3+5. Now let's simplify this. The final answer is 5x+8. That is the final answer!
Hope this helped!!! :D
Answer:
∠CAD ≅ ∠ACB
Step-by-step explanation:
The justification states "alternate interior angles theorem." Alternate interior angles would be inside the parallel lines and on opposite sides of the transversal. The only pair of angles in our choices that fits this definition is ∠CAD and ∠ACB
