Answer:
sin 33° = 0.545
Step-by-step explanation:
complementary angle to 57° is 33°
sin 33° = 0.545
Answer:
Since it's a right angled triangle,
taking 61 as reference angle,
cos61 = b/h
or, cos61 = b/8
or, b = cos61.8
so, b = 3.9 feet
The bottom of the ladder is 3.9 feet away from the side of the house.
Area of the rectangle: 14.5 x 22 = 319 square meters.
Area the goat can reach ( area of a circle): 3.14 x 2.5^2 = 19.625 square meters.
Now subtract the area of the circle from the area of the rectangle:
319 - 19.625 = 299.375 square meters. (Round the answer as needed.)
