T= 34
Explanation
So measure t equals measure s also since it’s a isosceles triangle!
Then we combine all the equations together and set it equal to 180 because every triangle is 180°.
3x-2 + 3x-2 + 9x+4 = 180
Now we combine like light terms
3x + 3x + 9x -2 -2 +4 = 180
15x= 180
Now that we simplify the equation we solve for x
15x/15= 180/15. Divide both sides by 15
X= 12
The problem ask what the measure of t is so we plug the 12 into the equation to find the measure
3x-2= 3(12)-2
36-2= 34
So the measure of t is 34°
