First of all, In an angle bisector, it is a line passing through the vertex of the angle that cuts it into two equal smaller angles.
Answer:
I'll explain below, just follow the directions. I can't directly draw it.
Step-by-step explanation:
find the length and the width of a rectangle whose perimeter is 18 ft
2L + 2W = 18
simplify, divide by 2
L + W = 9
L = (9-W)
:
whose area is 20 square feet
L*W = 20
Replace L with (9-W)
W(9-W) = 20
-W^2 + 9W - 20 = 0
Multiply by -1, easier to factor
W^2 - 9W + 20
Factors to
(W-4)(W-5) = 0
Two solutions
W = 4 ft is width, then 5 ft is the Length
and
W = 5 ft is the width, then 4 ft
You need to get the x’s by themselves. Subtract the 6 making 4x=2 1/2x +6. Then subtract the 2 1/2x making 1 1/2x=6. Finally you need to do 6/1.5=x. I did 1.5 because it is the same as 1 and 1/2z your answer will be 4.
Let n be the no. of sides
(n-2)*180/n=156
180n-360=156n
24n=360
n=15
so the no. of sides is 15
