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 x-intercept is when y=0, so we plug that in our equation,

. +12 on both sides to get

. Divide by -8 to get
Answer:
cos 52 = 11/alpha ---> alpha = 11/cos52 = 17.9
Area of the figure = 27 square units
Solution:
Number of full squares shaded = 24
Number of half squares shaded = 0
Number of more than half square shaded = 3
Number of less than half square shaded = 4
Area of the figure = Number of full square + Number of more than half square
+ Half of number of half squares

= 24 + 3
= 27 square units.
Area of the figure = 27 square units
