Answer:
#1 and #2: 60
#3 : x=1
Step-by-step explanation:
The sum of all interior angles in any triangle is always 180 degrees, thus we can easily solve each question.
#1: 180=85+35+? which gives us ?=60
#2: This triangle is the same as the previous one
#3: We know that 180=90+60+30x which means 30=30x which gives us x=1
