Answer: D. 64° and 90°

Steps:
A right triangle is a triangle with a 90° angle.

90° + 26° + x = 180°
116° + x = 180°
x = 180° - 116°
x = 64°

Answer:

D. 64º and 90º

Step-by-step explanation:

All triangles' angles add up to 180º.

A right triangle must have an angle that is 90º and it gives you that one is 26º so all you have to do is add those together and subtract that from 180º to find the last angle.

180 - (90 + 26) = 64º

So the two other angles of the triangle would be 90º and 64º.
