Okay so you know a straight line is equal to 180 degrees, so you set them up in an algebraic equation. (5x+2)+48=180 subtract 48 first to get 5x+2=132 Subtract the 2 this time to get 130. Now you end up with 5x=130. Here you divide 130 by 5 to get X=26. If you just need to find the degree of that angle tho you can stop after the first subtraction because the math tells you (5x+2)=132 degrees.

Answer is 3/72

multiply the denominator and numerator of 3/8 by 9 (27/72)
multiply the denominator and numerator of 3/9 by 8 (24/72)

this is to get the same denominator of 72

then just subtract 
27/72 - 24/72 = 3/72

I Need The Answer Plz!!! Geometry Is Hard!!!
Scorpion4ik [409]

Answer:

B. 10

Step-by-step explanation:

First, we need to recognize that the two triangles are similar (the triangle with a leg value of 21 and the triangle with a leg value of 4 and hypotenuse x)

Let's first label the leg of the second triangle as y.

Then, we can set up this equation

\frac{21}{y} =\frac{y}{4}

Cross multiplying gives us

84=y^2

So, y=sqrt(84) or 2 sqrt(21).

Now, using the pythagorean theorem, we get

4^2+2sqrt(21)^2=x^2

100=x^2

x=10

Geometry math question no Guessing and Please show work
Vera_Pavlovna [14]
IN ORDER TO FIND THE ANSWER:

Add up two of the values. If they are greater than the third, the lengths can make up a triangle.

3 + 9 = 12
12 > 14? No

3 + 5 = 8
8 > 7? Yes

1 + 2 = 3
3 > 3? No

4 + 4 = 8
8 > 8? No

The answer would be B.
