Answer:
The angle of elevation of the sun is 33.7⁰
Step-by-step explanation:
let the height of the tree, T = 10 foot
length of the shadow created by the tree, B = 15 feet long
Height of the tree and the shadow of the tree forms a right angle triangle with the remaining side that joins the two which is known as hypotenuse.
Let the remaining side, hypotenuse, L = ?
Apply Pythagoras theorem;
L ² = T² + B²
L ² = 10² + 15²
L ² = 325
L = √325
L = 18.03 ft
The angle of elevation of the sun, is the angle facing the height of the tree with the length of the shadow of the tree as adjacent of the triangle.
Let the angle of elevation = θ
tan θ = opp / adj
tan θ = 10 / 15
tan θ = 0.66667
θ = tan ⁻¹ (0.66667)
θ = 33.7⁰
Therefore, the angle of elevation of the sun is 33.7⁰
Answer:
D. 768

The answer is D. 768
Answer:
D
Step-by-step explanation:
0.000009 = 9×10^-6
0.00000003 = 3×10^-8
9×10^-6 / 3×10^-8 =
9/3 × 10^(-6+8) = 3 × 10^2
Answer:
2%
Step-by-step explanation:
Chloe's simple interest for 1 year is $4. You can get this by subtracting the amount she invested from the total amount she got after one year.
Now that we know the simple interest, we can now get the simple interest rate or<em> simple percent interest per year </em>by dividing $4 by $200.
Let's change 0.02 into a percentage.
This means that every year, her investment will earn a <em>2% simple interest.</em>
You have the answer right there near the end.
2-1/2 x 10 = 25 miles.
