Answer:

x = 19

Step-by-step explanation:

A circle has a total of 360 degrees. Because central angles are congruent to the degree measures of their arcs, and because of vertical angles we can construct the equation :

5x+37+5x+37+3x-9-9=360

We can simplify this to :

8x+28=360

Subtract 28, divide 8, and x is 19

Use the Pythagorean theorem to find the length of the leg in the triangle below. side a is 35 , and side c is 21. What is B?

garri49 [273]

Answer:

b=-784!

Step-by-step explanation:

If pythagorean theorem is the following (see below), then we can work backwards in order to solve for b!

$a^{2} +b^2=c^2$

$35^2 +b=21^2\\1225+b=441$

Now all that's left is to subtract 1225 and we should have our answer!

$b=-784!$
