Answer:
m = 8
n = 40°
Step-by-step explanation:
The rule for angles in a triangle is that they all need to add up to 180°, so you can make the three expressions equal 180 and solve:
x + 10 + x + 2 + 9x - 8 = 180
11x + 4 = 180
- 4
11x = 176
÷ 11
x = 16
So your answer is 16
I hope this helps!
Would it help if you wrote it as
?
Then you can cross multiply if you know how to do that.
1*x = (-11)(-3)
x = 33 but what happened to the 2 minus signs?
Remember that a ( - ) times a ( - ) = a plus. The two minus signs become a plus.
ok its 11 sqrt 6
because if sqrt 6 is x, and 5x +6x=11x
so its 11 sqrt 6
