Question

Find the missing value and please shoe how

Answer 1

20 degrees

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

Answer 2

20

Explanation:

? = 180 - 60 - (180 - 80) = 180 - 60 - 100 = 20
