PLEASE HELP ME SOLVE FOR X

Mathematics
1 answer:
jeka57 [31]3 years ago

Looks like the labeled angle is bisected, in which case we can apply the angle bisector theorem. For this triangle, it says

\dfrac x3=\dfrac{x+2}{x+4}

Solve for x:

x(x+4)=3(x+2)

x^2+4x=3x+6

x^2+x-6=0

(x+3)(x-2)=0

Then either x=-3 or x=2, but since x is a length, it must be positive. So <em>x</em> = 2.

A rectangular parking lot has a length 20 H more
leva [86]

Let the width = X

The length would be X + 20

Area = Length x width:

2400 = x * (x+20)

Simplify:

2400 = x^2 + 20x

Subtract 2400 from both sides:

x^2 + 20x - 2400 = 0

Factor:

(x-40) (x+60) = 0

Solve for both x's:

x = 40 and x = -60

The dimensions of a parking lot have to be positive values so you would use x = 40.

The width = x = 40

The length = x +20 = 40+20 = 60

The dimension of the parking lot is 40H x 60H
