A convex pentagon has three right angles. The other two angles are congruent to each other. What is the measure, in degrees, of one of these other angles?

Sum of internal angles =  (n-2)* 180 = 540

 

Subtract the three 90 degree angles     540 - 3 * 90 = 270

270 degrees is two remaining angles total        each   135 degrees
