Answer:Exterior angles of a polygon sum to 360

94 + 56 + 4.5x + x + 1.5x = 360

150 + 7x = 360

7x = 210

x = 30

#5

Sum of interior angles of a pentagon is:

(5 - 2)*180 = 540

Sum of interior angles of a given pentagon:

72 + 3x + 89 + 99 + 2x = 540

5x + 260 = 540

5x = 280

x = 280/5

x = 56

A camper wants to know the width of a river. From point A, he walks downstream 120 feet to point B and sights a canoe across the
astraxan [27]

Answer:

53 feet   (to the nearest foot).

Step-by-step explanation:

This forms a right angled triangle with the adjacent side to the 24 degrees angle  and  the opposite side = width of the river.

So we have tan 24 = opposite side / adjacent side.

tan 24 = x / 120 where x = the width of the river.

x = 120 tan 24

x =  53.4 feet.
