Answer:
equation: 90°+(x+34°)+(x+34°) = 180°
x= 11°
measure of the C: 45°
Explanation:

First of all, we know that all of the angles in a triangle are equal to 180°. As you can see in the triangle, one of the angles has that little right angle symbol (the tiny square), meaning it's equal to 90°. Therefore, we can make the equation:
90°+(x+34°)+(x+34°) = 180°
Next, you can use algebra to solve that equation, to find x.
90°+(x+34°)+(x+34°) = 180°
90°+2x+68°= 180°
158°+2x=180°
2x=180°-158°
2x=22°
x=11°
Now that we know the value of x, which is 11°, we can plug that into the equation of Angle C. The equation of Angle C is x+34°. So, it becomes
11°+34°
= 45°
