Question

PLEASE HELP Me Thank u!!

Answer 1

Answer:

Length = 13

x = 80

Step-by-step explanation:

Question One

Let the width = x

Let the length = x + 5

Area = 104

Equation

Area = L * W

Area = (x+5)*x

Solution

x ( x + 5) = 104                  Remove the brackets

x^2 + 5x = 104                  Subtract 104 from both sides.

x^2 + 5x - 104 = 104 - 104

x^2 + 5x - 104 =  0            Factor the equation    

(x + 13)(x - 8) = 0

Only x - 8 = 0 works

x = 8

The width = 8

The Length = 8 + 5 = 13

Question Two

Draw AP

<BAP = 20o                     The triangle (APB) is isosceles: 2 sides are radii

<BPA = 180 - 20 - 20      The three angles of a triangle = 180

<BPA = 140                      Combine

Similarly <CAP = 140       Go through exactly the same steps.

<BPA + <CAP + X = 360  The total of the 3 angles in the center = 360

140 + 140 + X = 360         Combine

280 + X = 360                 Subtract 280 from both sides.

x = 80
