Answer:
Angle A is 118°
Step-by-step explanation:
All angles in a circle add up to 180, so this means that all the measurements of the three angles add to 180:
x + 2x + 13 + x - 8 = 180
Clean it up:
3x + x + x + 13 -8
5x -5 = 180
To isolate the 5x, you need to move the +5 over to the other side, making it a negative 5:
5x = 180 - 5
5x = 175
Now divide each side by 5 to get the value of 1x:

x = 35
So angle A is:
3x + 13
3(35) + 13 = 118
<h3>So angle A is 118°</h3>

14 because Josh’s dhdjd dhjdnf fjdndnf didn’t did f d f f f f f d f f f f
4:2 1/2
Divide both sides by 2 1/2:
4/(2 1/2) :1
(4/1) / (5/2) :1
4/1*2/5 :1
8/5:1
1 3/5 :1
Hope this helps :)
Answer:
Irrational
Step-by-step explanation:
Since there is no integer that can be multiplied by itself to make 57, the square root of 57 is irrational. (T/F): The square root of 45 is a rational number. False. EXPLANATION: Only perfect squares have rational square roots.
