For this case we have the following equation:

We apply distributive property on the left side of the equation, taking into account that:

So:

Subtracting 3m from both sides of the equation:

Equal signs are added and the same sign is placed:

We subtract 6 from both sides of the equation:

We divide between -4 to both sides of the equation:

Thus, the solution of the equation is

Answer:
x=29. Angle C= 93
Step-by-step explanation:
3(x+2)= 3x+6.
3x+6+52+35= 3x+93.
180-93=87.
87/3= 29. So that means x=29.
for proof you can do 3(29)+93 and you'll get 180.
For angle C; 3(29+2)= 3x31. 31x3= 93.
Angle C= 93 degrees.
Answer:
20
Step-by-step explanation:
the triangles are similar so the sides are in proportion
(x/10)=(12/6)
6x=10*12
x=10*12/6=20
