Answer:
Measure of the smallest angle = 35 degrees.
Step-by-step explanation:
As it is a right triangle the values of the 2 smaller angles will add up to 90 degrees.
So the 2 angles can be written as x and 90-x and we have:
(90 - x) - x = 20
-2x = 20 - 90 = -70
x = 35.
So the 2 angles are 35 and 55 degrees.

10/4 + 1/3 = 17/6
step 1: reduce the fraction with 2:
5/2 + 1/3
step 2: write all numerators above the common denominator 6:
15 + 2/ 6
step 3: add the numbers:
17/6
