The length of three sides of a triangle are 3x + 1/2, 2x +1/4, and x +1/2.

1 answer:

6 0

Answer: x= 41

Explanation: Angles 1 and 2 have to equal 180° since they are supplementary. So you put 3x+2x-25=180, you then add like terms. 5x-25=180 Then you have to isolate x, so you add 25 to both sides of the equation. 5x=205, then you divide both sides by 5. So your answer is x=41.

You can check to make sure by plugging in x for 41 .

Hope this helps!
