Hello again! So we will be using the pythagorean theorem (

) to solve for the bottom leg of the triangles. After we do that, we'll subtract the value of the legs from 31, and that'll be x.
Plug in 17 and z (or any variable that isn't x) into the leg variable and 19 into the hypotenuse variable, and from there we can solve.

Solve the exponents to get

Subtract 289 on each side to get

Lastly, square root each side of the equation and your answer should be

(To get more accurate answers, you shouldn't round until the end of the problem)
Nextly, we will need to subtract

from 31. And since there are 2 triangles, you'll need to multiply

by 2.
In short, x = 14.0
Answer:
The third graph is your answer.
Step-by-step explanation:
I included a graph below with the correct graphing.
So the total is 120. You want 1/6 of those.
So do (1/6)*120
You get 20.
YAY
Answer:

Step-by-step explanation:
using the rule of exponents
= 
note that 6 =
, then
=
= 
<u>p</u><u>=</u><u>7</u><u>0</u><u>°</u>
<u>q</u><u>=</u><u>3</u><u>2</u><u>°</u>
<u>r</u><u>=</u><u>3</u><u>8</u><u>°</u>
Answer:
Solution given:
r=38°[inscribed angle on a same arc are equal]
p=½*140°=70°[inscribed angle is half of the central angle]
<OBA=38°[base angle of isosceles triangle]
again
<C=<B[inscribed angle is half of the central angle]
70°=<OBA+q
70°=38°+q
q=70°-38°
q=32°
