Answer:
m<C = 119°
Step-by-step explanation:
Create an equation to find the value of x.
(9x - 26)° = (2x - 12)° + (4x + 43)° (exterior angle theorem of a ∆)
Solve for x
9x - 26 = 2x - 12 + 4x + 43
Add like terms
9x - 26 = 6x + 31
9x - 6x = 26 + 31
3x = 57
Divide both sides by 3
x = 19
✔️m<C = 4x + 43
Plug in the value of x
m<C = 4(19) + 43
m<C = 76 + 43
m<C = 119°
Answer:
x=7, y= 8
Step-by-step explanation:
x+y=15
x+2y=23
Subtract the first equation from the second equation to eliminate x
x+2y=23
-x-y=-15
--------------------
y = 8
Now we can find x
x+y = 15
x+8 = 15
Subtract 8 from each side
x+8-8=15-8
x = 7
