let me know if this helps guys my husband helped me with it he is good at math
Answer:
15. x = 112 degrees
18. x = 120 degrees
Step-by-step explanation:
<u>15.</u>
A triangle's angles always equal 180 degrees so we can find the two unknown angles by subtracting 44 from 180 and then dividing it by 2.
2a + 44 = 180
2a = 136
a = 68
Each unknown angle equals 68 degrees. The line from 44 degrees to x degrees segments a line that has a 180 degree angle so we can subtract 68 from 180 to get x.
x + 68 = 180
x = 112
<u>18.</u>
We can use the same concept here but now every angle equals each other so we can divide 180 by 3 to get the measure of those angles.
3a = 180
a = 60
Now we do the same thing as last time to find x.
x + 60 = 180
x = 120
