If triangle ABC has the following angle measurements, what is the set-up to solve for x? ∠A= 4x - 17

∠B= 3x + 8

∠C= x + 13

4x - 17 + 3x + 8 + x + 13 = 180

4x - 17 = 3x + 8 + x + 13

4x - 17 - 3x + 8 - x + 13 = 180

4x - 17 - 3x + 8 - x + 13 = 180

A

Step-by-step explanation:

The answer is the first one. We've used that in previous questions.

B is wrong. It needs to be equal to something (180 in this case). B is also saying that the first angle is = to the sum of the other two. Not so.

C is wrong. the third angle's x term has to be plus.

D has the same problem.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
