Answer:

Explanation:

The entire value of the triangle is 180 degrees.

If you subtract 25 from 180 you are left with 155

Then Subtract 90 from 155 which will leave you with 65

Go on to subtract 11 from 65 having to be with 54 degrees left

Finally you will dived 54 by 3 and you are left with 18

3 x 18 = 54

54 + 11 = 65

Therefore x will equal to 65 degrees

Answer:

x=17

Explanation:

we know the 25 + 90 = 115 so we need the other one to make it 180 degrees.

180-115= 65

so we need 65 more degrees to get 180

now 3x + 11= 65 first step subtract 11 on both sides

you now get 3x = 54 then 2nd step is divide 3 on both sides

and now you get x=17 so
