50'

Step-by-step explanation:

Heres the image of the problem's solution.

Answer 2

Answer:

Let the other two unknown angles be x and y

We know the sum of all the angles of a traingle is 180°

Therefore, 60°+x+y=180°

If we consider x=70° and y=50° then according to the question 70-50=20

So, the sum of 70+50+60 is equal to 180° which satisfying the property of a traingle.

Therefore, the measure of the smallest angle is 50°
