If the drawing of your octagon (or whatever) has been separated into triangles, and one triangle's area<span> is labeled, then you do not need to know the apothem. Just take the </span>area<span> of that one triangle, and multiply by the number of sides in the original </span>polygon<span>.</span>
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
2x+10=0
subtract 10 from both sides
2x=(-10)
divide 2 from both sides
x=-5
(2x^2-x^2)= x^2
(1+7) = 8
X^2 + 8
Answer:
No
Step-by-step explanation:
a proportional relationship must have a constant ratio to another quantity.
have a nice day and mark me brainliest! :)
