Answer:
8 ft up or 32 ft down depends if she goes above sea level or down sea level
Step-by-step explanation:
if you take the 2 away and subtract 10 from 20 you get 10 then subtract the remaining two
If she whent down you would add 12 + 20
Step-by-step explanation:
19 is the greatest value
Answer:
46.7 degrees.
Step-by-step explanation:
According to the given information, triangle DEF is a right triangle with angle F as the right angle. We are trying to find the measure of angle D.
We are given the opposite side length (6.4 feet) and the hypotenuse (8.8 feet), so we can use sine to calculate the angle measure (SOH = Sine; Opposite over Hypotenuse).
sin(D) = 6.4 / 8.8
sin(D) = 64 / 88
sin(D) = 8 / 11
D = arcsin(8 / 11)
D = arcsin(0.72727272727272727272727273)
D = 46.65824177.
So, the measure of angle D is about 46.7 degrees.
Hope this helps!
