Answer:
86.6
Step-by-step explanation:

Here, AB represents height of the building, BC represents distance of the building from the point of observation.
In the right triangle ABC, the side which is opposite to the angle 60 degree is known as opposite side (AB), the side which is opposite to 90 degree is called hypotenuse side (AC) and the remaining side is called adjacent side (BC).
Now we need to find the length of the side AB.
tanθ = Opposite side/Adjacent side
tan 60° = AB/BC
√3 = AB/50
√3 x 50 = AB
AB = 50√3
Approximate value of √3 is 1.732
AB = 50 (1.732)
AB = 86.6 m
So, the height of the building is 86.6 m
Step-by-step explanation:
It's 6r+5y. But it's not in the option
Answer:
(c) Pi/4
Step-by-step explanation:
3pi/4 = (3 x 180) / 4 = 135 degrees
135 degrees is equivalent to (180 degrees - 135 degrees) 45 degrees
45 degrees = Pi/4
Therefore, the reference angle of 3pi/4 is Pi/4
Thus, the correct option is (c) Pi/4
Answer:A
Step-by-step explanation:
When graphed it is the only one to semi-complete the pattern
Answer: Therefore, Option 'A' is correct.
Step-By-Step explanation:
Since we have given that
Amount spent on equipment = $36
Amount spent on fees = $158
Amount spent on transportation = $59
Total amount spent by them is given by

Percent cost of equipment of the total amount is given by

Percent cost of fees of the total amount is given by

Percent cost of transportation of the total amount is given by

Hence, Percent cost of the total spent on each is
14%, 62%, 23%.
Therefore, Option 'A' is correct.
