Question 672865
The sum of angles in a triangle = 180 degrees

one angle is 35
let x=another angle
the third angle is 2x-26

35+x+2x-26=180
combine like terms
9+3x=180 
subtract 9 from both sides
3x=171
divide both sides by 3 to get the value of x
x=57

2(57)-26=88

the other two angles are 57 degrees and 88 degrees

check work
35+57+2(57)-26=180
35+57+114-26=180
180=180
