Perimeter = Side + Side + Side
Side 1 = x
Side 2 = x + 7
Side 3 = 2x-7
Plug into the equation:
84 = x + (x + 7) + (2x-7)
84 = x + x + 7 + 2x - 7
Combine like terms:
84 = 4x
Divide by 4 and solve for x:
21 = x
Side 1 = 21
Side 2 = 28
21+7=28
Side 3 = 35
21(2) - 7 = 42 - 7 = 35
I think the answer is 76 because the tree is halfway between building and stake
or it could be 57 either one but 70% it is 76
Answer:
$28.12
Step-by-step explanation:
$9.19 x 40 = $367.60 x 7.65% = $28.12
Divide both sides by 1.5
1.5x = 3
x = 2
Check the equation by plugging in the 2.
1.5(2) = 3
3 = 3
Factor out cosx: cosx(sinx-2)=0
cosx=0 or sinx-2=0
cosx=0 or sinx=2
the largest value of sinx is 1, sinx will never be 2, so cosx=0, x=π/2 or 3π/2 are the two answers.
