Answer:
see below
Step-by-step explanation:
Part A
Angles 1 and 5 are alternate angles (z angles), which means they are equal.
Similarly, angles 3 and 6 are alternate (z angle), which means they are equal.
Part B
Angles on a straight line add up to 180°.
Let the second side be equal to x
Then the first side is x-5
The third side will be x-5-2 = x-7
Therefore you add all the following sides and equate it to 42 yards. Ie x+x+5+x-7 = 42
3x=44
X= 44/3
Therefore the second sides length is 44/3
The first sides length is 44/3 -5 = 29/3
The third side is 44/3 -7 = 23/3
