109°
Step-by-step explanation:
subtract 180 from 71 and you will get 109°
Answer:
the answer is 24
Step-by-step explanation:
72/y=3
72/3
24
Answer:
108 degrees
Step-by-step explanation:
Since angles A and B are supplementary, they both add up to 180. Angle A = 7x+10, and angle B = 7x-26. You can set up the equation A + B = 180, and then plug in angles A and B, which gives you 7x+10 + 7x-26 = 180. Then you just need to isolate x:
Combine like terms: 14x - 16 = 180
Add 16 to both sides: 14x = 196
Divide both sides by 14: x = 14
Now that you know x, you can plug it into the expression for angle A (7x+10):
A = 7(14) + 10 = 98+10 = 108

7x−3y=3 Important: you have two -3y terms. Mult one eqn by -1 to
obtain +3y, and then add the 2 equations together:
4x - 3y = 12
-7x+3y = -3
----------------
-3x = 9, so x = -3. Subst. -3 for x in the first original equation to find y:
4(-3) - 3y = 12, or -3y = 24. Then y = -8.
Solution is (-3, -8).
It's important that you check this answer by subst. (-3, -8) back into either one of the original equations.

Hello there!
A^2 + B - C / M; A = 6, B = 8, C = 5, M = 3.
Plug in our numbers.
6^2 + 8 - 5 / 3
36 + 8 - 5 / 3
44 - 5 / 3
39 / 3
13.
Your answer is 13.
I hope this helps!
