Answer:
20 degrees
Step-by-step explanation:
The sum of all the angles in a triangle is 180 degrees.
In triangle SUT, you are given angle 60.
To find angle SUT, subtract 180 - 80 = 100 because 80+100 equals 180 and angle SUT and ZUT are supplementary. (equals 180 when added together)
Now we have 60 and 100
add them ------> 60+100= 160
then subtract ------> 180-160 = 20
