Sum of two angles that are supplementary = 180°
Let the smaller angle be = x
Using this let us find the measures of the smaller angle and bigger angle .
∴ The measure of the two angles are = 21° and 159° .
Answer:
42=2[{45-3(14-21)}+4]
42=2[{45-3×-6}+4]
42=2[{45-18}+4]
42=2[{27}+4]
42=2[27+4]
42=2×31
42=62
Z is 66. If you want an explanation, I could give it to you, FYI.
