Find the measure of ∠C if

V125BC [204]

$(32x+20) + (72x+20) + (52x+40) + (32x+10)=180 \\ 32x+72x+52x+32x +20+20+40+10 =180 \\ 188x+90=180 \\ -90 \\ 188x=90 \\ /188 \\ x=0.478
$
then $52(0.478)+40 \\ 24.856+40=64.856
$
∠C = 64.856

The rectangle below has an area of x^2-6x-7 square meters and a width of x-7 meters

Illusion [34]

Complete Question:

The rectangle below has an area of x^2-6x-7 square meters and a width of x-7 meters. What expression represents the length of the rectangle?

Answer:

<h3>The expression represents the length of the rectangle is (x + 1) meter</h3>

Solution:

Given that,

$\text{Area of rectangle} = x^2 - 6x - 7 \\\\Width = x - 7$

TO FIND: LENGTH = ?

We know that,

$Area\ of\ rectangle = length \times width \\\\Therefore\\\\x^2 - 6x - 7 = length \times x - 7\\\\length = \frac{x^2 - 6x - 7 }{x - 7 }\\\\length = \frac{(x-7)(x + 1)}{x - 7}\\\\\text{cancel out x-7 from numerator and denominator} \\\\length = x + 1$

Thus expression represents the length of the rectangle is (x + 1) meter
