Please find the attached diagram for a better understanding of the question.
As we can see from the diagram,
RQ = 21 feet = height of the hill
PQ = 57 feet = Distance between you and the base of the hill
SR= h=height of the statue
=Angle subtended by the statue to where you are standing.
= which is unknown.
Let us begin solving now. The first step is to find the angle which can be found by using the following trigonometric ratio in :
Which gives to be:
Now, we know that and can be added to give us the complete angle in the right triangle .
We can again use the tan trigonometric ratio in to solve for the height of the statue, h.
This can be done as:
Thus, the height of the statue is approximately, 8.45 feet.
Answer:
A. Obtuse
Step-by-step explanation:
Well we can cross out C and D just by looking at the triangle because the triangle is not equal and there is no right angle.
Also it is not B an acute because not all the angles are acute.
Hence, the answer is A. Obtuse
Answer:
If it took the motorcycle 2 hours to cover 20km, then the average speed is 10km per hour.
Speed is equal to distance over time. So 20km divided by 2 hours is 10 km per hour.
Answer:
The expression simplifies to .
Step-by-step explanation:
The expression
can be rearranged and written as
In this form the terms in the numerator and in the denominator cancel to give
The are present both in the numerator and in the denominator, so they also cancel, and the fraction simplifies to , so finally our expression becomes:
Which is our answer:)
