What’s the answer for this equation

C = 40 degree

AB = 5.785  = 55.79, = 5.8 = 6  (4,3,2,1 significant figures)

BC =  11.748 = 11.75 = 11.7=12  (4,3,2,1 significant figures

Step-by-step explanation:

ASA  Angle Side Angle (given)

90-50=40 degree as all angles within triangle add up to 180 degree

C = 40 degree

AC (given = 9

AB = A/H = 9xcos(50) = 5.8 measure

BC = O/H = 9 / sin (50) = 11.7 measure

32

step-by-step explanation:

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.
