Answer:

Your teacher is correct.

Step-by-step explanation:

So first we would have to find what A is equivalent to which is 48. This is because 180 - 132 = 48. Since we know that 132 is a supplementary angle, there has to be another supplementary angle that results in the sum of 180.

With this information in mind, we can create the expression:

2x + 4x + 48 = 180 (A triangle is equal to 180 degrees)

Now simply the equation:

6x + 48 = 180

6x = 132

6x/6 = 132/6

x = 22

Angle C = 44

Angle B = 88

seropon [69]

Answer:

the answer is: $x=13$

Step-by-step explanation:

We get the answer using Pitagoras.

$5^2+12^2=x^2$

$x=\sqrt{5^2+12^2}=\sqrt{25+144}=\sqrt{169}=13$

a rectangle has horizontal sides of 3 (x-2)ft and vertical sides of 4x-7+(-2x) ft finde the value of x so that the rectangle has

Lynna [10]

Based on the given horizontal and vertical sides of a rectangle and its perimeter, the value of x in the expression is 6

<h3>Perimeter of rectangle</h3>

Perimeter of rectangle = 2(length + width)

Perimeter of the rectangle = 34 ft

Length of the rectangle = 3(x - 2) ft

= 3x - 6

Width of the rectangle = 4x - 7 + (-2x)

= 4x - 7 - 2x

= 2x - 7

Perimeter of rectangle = 2(length + width)

34 = 2{(3x - 6) + (2x - 7)}

34 = 2(3x - 6 + 2x - 7)

34 = 2(5x - 13)

34 = 10x - 26

34 + 26 = 10x

60 = 10x

x = 60/10

x = 6
