Answer:
(a) Because it is an exterior angle
(b) The measure of angle 2 is 72°
Step-by-step explanation:
Angle 2 is an exterior angle because it is adjacent to the interior angle 1, and an exterior angle is equal to the sum of the measures of the two nonadjacent interior angles:
<2=30°+42°
<2=72°
area of a triangle is 1/2×h×b
1÷2×12×13
=78
