A 109 ft tree casts a shadow that is 130 ft long. what is the angle of elevation of the sun?

Answers

Answer 1
Answer:

The angle of elevation of the sun is approximately 40 degrees

The scenario forms a right angle triangle.

The height of the tree is the opposite side of the right angle triangle formed .

The shadow casted on the ground is the adjacent side of the triangle.

Therefore, using trigonometric ratio, the angle of elevation can be found as follows:

height of the tree = 109 ft

length of the shadow = 130 ft

let

the angle = ∅

tan ∅ = opposite / adjacent

tan ∅ = 109 / 130

∅ = tan⁻¹ 0.83846153846

∅  = 39.978520842

∅ ≈ 40°

Answer 2
Answer: Answer: 40°


Explanation:

\tan(\theta) = \cfrac{109}{130}

\theta = 40 \textdegree

8x-9y=11 Solve for y.

Answers

8x-9y=11
-9y=-8x+11
9y=8x-11
y=8/9x-11/9
sorry, thats as simplified as it can get with 2 variables in the equation

Answer:

y = 8/9x + -11/9

Step By Step:

Let's solve for y.  8x−9y=11

Step 1:

Add -8x to both sides.  

8x−9y+−8x=11+−8x

−9y=−8x+11

Step 2:

Divide both sides by -9.

-9y/-9 = -8+11/-9

y = 8/9x + -11/9

Which is bigger 3/7 or 4/9

Answers

4/9 is bigger because if you convert
3/7 and 4/9 into there common denominator which is 63.
3/7= 27/63
4/9= 28/63 so 4/9 is bigger
