Pls answer i’m begging

75

Step-by-step explanation:

Angles in a triangle add up to equal 180

That being said we can find the missing angle by subtracting the measures of the given angles from 180

Thus missing angle = 180 - 34 - 71

180 - 34 - 71 = 75

Which means that the missing angle = 75

? = 180 - (angle 1 + angle 2)

? = 180 - (71 + 34)

? = 180 - 105

? = 75°

=> To check is the answer is right, add all 3 angles together and their sum should be 180°

Hope this helps!

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
