Answer:
a.) 70*
b.) 60*
Step-by-step explanation:
a.) An isosceles triangle has two angles that are equal. The one other angle is 40*, meaning you have to subtract that from 180 and then divide by 2.
b.) An equilateral triangle has three equal angles. Divide 180 by 3.
a)180-40
=140÷2
=70
answer 70°
b)180÷3
=60
60°
each triangle things add up to 180
