Question

in triangle ABC, A=(3x + 7), B =(2x-8), c=(5-x)

solve for x

Answer 1

If these are the angles of the triangle you would add them up which would eventually equal to 180.

\(\huge\bf{(3x+7)+(2x-8)+(5-x)=180}\)

Answer 2

\(\Large\bf{(3x+7)+(2x-8)+(5-x)=180}\)

Sorry the other was to big

Answer 3

3x+7+2x-8+5-x=180
3x+2x-x+7-8+5=180

you can do the rest! :D

Answer 4

Simplify both sides of the equation.
(3x + 2x + −x) + (7 + − 8 + 5)=180(Combine Like Terms)
4x + 4=180

Answer 5

Subtract 4 from both sides.

Answer 6

4x + 4 − 4 = 180−4

Answer 7

4x=176

Answer 8

Divide both sides by 4.

Answer 9

4x/4 =176/4

Answer 10

x=44

Answer 11

So.....Your answer is x = 44
