Answer:
Area = 8.1902ft² (Rounded up to 4 decimal places)
Step-by-step explanation:
Let side a = 7.2ft, side b = 3.4ft and angle β = 42°
Area of the triangle will be given by:
1/2 × a × b × sinβ
Area = 1/2 × 7.2 × 3.4 × sin 42°
Area = 8.1902 ft² (Rounded up to 4 decimal places)
Answer:
Apply trigonometric function for triangle ABC:
7.
sin A = BC/BA = 6/7.2 = 0.83
A = arcsin(0.83) = 56.44
8.
tan B = AC/BC = 4/6 = 0.67
B = arctan(0.67) = 33.69 deg
Hope this helps!

There are a total of 8 balls
The probability of drawing a white ball is 4/8 on the first draw.
If you replace the ball then the probability will still be 4/8 for a white ball, since these events are independent of each other you multiply 4/8 x 4/8 = 16/64 or 1/4 then the probability of drawing at least 1 red ball with replacement is 1 - 1/4 = 3/4
Now without replacement:
the probability of drawing a white ball is 4/8 since you don't replace the ball then the probability of drawing a white ball the second time is 3/7 again multiply these two probabilities: 4/8 x 3/7 = 12/56 the the probability of drawing at least 1 red ball is 1- 12/56 = 44/56 or 11/14
Answer:
Height = 6.5 in.
Step-by-step explanation:
936π = π r^2 h
936 = r^2 h
r = 24/2 = 12 so
144 h = 936
h = 6.5 in.
