Answer:
466.30 ft
Step-by-step explanation:
Given in the question,
the angle of elevation of the top of a tree from ground = 25°
horizontal distance between angle of elevation and tree = 1000ft
To find,
height of tree( vertical distance from ground to top of tree)
As we can presume for the question that the whole scenario makes a right angle triangle. So, we will use trigonometry functions
Tan Δ = opposite / adjacent
Tan25°= height / 1000
height = 1000 * Tan25°
height = 1000 * 0.466
height = 466.30 ft
So, the height of tree = 466.30 ft
Answer:
x-intercept: 7; y-intercept: −9.
Step-by-step explanation:
The entire circle has a central angle of 360°.
Because the radius is 6 mi, the area of the circle is
π(6)² = 36π mi².
The sector has a central angle of 60°, therefore it occupies 60/360 = 1/6 of the area of the circle.
The area of the sector is
(1/6)*36π = 6π mi² = 18.85 mi²
Answer: 6π mi² or 18.85 mi².
The answer is -3.9364916731.
Answer:
38 1/4
Step-by-step explanation:
First I convereted 8 1/2 and 4 1/2 to fractions, because it is easier for me, which gives you
8.5*4.5
Multiplying this out you get 38.25, which is equal to 38 1/4.
If you do it by fractions you convert them to inproper fractions.
8 1/2= 17/2
4 1/2= 9/2
You then multiply and get 153/4
When you divide 153 by 4 you get 38 1/4
