You might be able to figure this out for yourself, based on the following information:* The angles of a triangle must add up to 180 degrees.
* A right angle has a measure of 90 degrees.

All triangle angles add to 180 degrees. Since one is 38 and the right angle is 90, the third angle is 180 -38-90 = 52 degrees
Suck it
No - the sum of the interior angles of a triangle mustadd up to 180 degrees. Since you already have one angle of 90 degrees, the sum of the other two angles must also total 90. 38+54 is 92 !
(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
