Angle D is equal to Angle B because AB and DE are parallel to each other.


AD is a straight line so the (2) 2x angles and 72 degrees need to equal 180.

Setting up the equation you have:

2x + 2x + 72 = 180

Simplify:

4x + 72 = 180

Subtract 72 from each side:

4x = 108

Divide both sides by 4:

x = 108 / 4

x = 27

elena55 [62]
D = 0.32


d - 8 / 5 = -4d

d - 1.6 = -4d
d + 4d = 1.6
5d = 1.6
d = 0.32

This is an exact question in my math textbook. It should be correct.

What is the value of x?<br><br> What is the measure of
liraira [26]

Answer:

x is 10

Step-by-step explanation:

Form the diagram, you can see that UV is parallel to TS, this means that <UVS  = < UTS

Given

<UVS = 5x + 38

<UTS = 12x - 28

Since the sum of opposite angle of a quadrilateral is 180 degrees, hence;

5x + 38 + 12x - 28 = 180

Collect like terms

5x + 12x - 28 + 38 = 180

17x + 10 = 180

17x = 180-1-

17x = 170

x = 170/17

x = 10

hence the value of x is 10

Jerry is buying a new large screen television for his game room. He knows that the diagonal of the television measures 42.1 inch
bixtya [17]
Remember that the area of a rectangle is length times width; since we don't know the width, we'll use the Pythagorean theorem to find it first:
l= \sqrt{h^{2}-c^{2}  }
Where l is the leg, and h the hypotenuse. We know that one of the legs, the base has a measures 34.3 inches and the hypotenuse a measures 42.1 inches.
Replace the values to get:
l= \sqrt{42.1^{2}-34.3^{2}  }
l=24.4=w
Now that we know the width (w), we just net to multiply it by the length to get our area:
A=(24.4)(34.3)=836.9

We can conclude that the correct answer is <span>B) 836.9 in.</span>
