Question

Find the missing angle measure. Then classify the triangle by its angles.

A: 35°, right
B: 35°, obtuse
C: 35°, scalene
D: 35°, acute

Answer 1

B: 35*, obtuse

Explanation:

Because a triangle can only add up to 180* you subtract 145* from that and you're left with 35*. Because the triangle had an angle over 90* it is an obtuse triangle.
