Sagot :
Everything is right until the 3x +90=180
you want to subtract 90 to get:
3x=90
the divide by 3
x=30
So the measure for angle t would be 60 degrees

Your first two lines are beautiful. That's exactly
the right way to approach this:
2x + 90 + x = 180
3x + 90 = 180 .
But then I don't know what your third line means,
or even where it came from.
Here where you need to go after the first two lines:
(second line) . . . 3x + 90 = 180 .
Then, subtract 90 from each side: 3x = 90
Divide each side by 3 : x = 30
Angle ' T ' = 2x = 60 degrees.
Angle ' V ' = x = 30 degrees.
Check: 60 + 90 + 30 = 180 degrees yay !
