Step-by-step explanation:
Answer:h
Step-by-step explanation:
j
For 3. It is the fourth choice. This is because angle DGF is vertical angle and thus equal to angle EGB. Then angle BGF is supplementary to this angle.
So your answer is EGB+BGF=180
For 4. It is the first choice of 62 ft. It is the midpoint so is half the total line segment.
The two numbers are 8 and 12.
When added, you get a sum of 20.
When multiplied, you get a product of 96.
