125°

Step-by-step explanation:

This geometric has 6 angles and as given the sum of interior angles for this shape is (6 - 2) × 180

4 × 180 = 720

117 + 124 + 102 + 145 + 107 + x = 720

595 + x = 720

x = 125

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
