Answer:
x = 20
Step-by-step explanation:
m<ABC and m<CBA are complementary angles which means their sum is 90 degrees:
2x + 3x - 10 = 90 add like terms
5x - 10 = 90 add 10 to both sides
5x = 100 divide both sides by 5
x = 20 to find the angles replace x with 20
m<ABC = 40 and
m<CBA = 50

5x+9-3x=18+15
First of all, in the case of a equation that has one vatiable having one power ,you need to bring all the variable together in one side.
5x-3x=18+15-9
0r,2x=18+6
Or,2x=24
Or,x=24/2
Or,x=12
So it's the solution..
