Answer:
I can answer the type of angle: Acute
Step-by-step explanation:
It's less than 90 degrees, so it's
Step-by-step explanation:
of what where is the question
Answer:
18°
Step-by-step explanation:
1. ∠A and ∠B are complementary angles, so they add up to 90°.
- This means that 2x - 4 + 5x + 17 = 90
2. To find the measure of ∠A, we first have to solve for x.
3. (Solving)
Step 1: Simplify both sides of the equation.
Step 2: Subtract 13 from both sides.
Step 3: Divide both sides by 7.
4. Now that we know x = 11, let's plug that value into (2x - 4) to find the measure of Angle A.
Therefore, the measure of ∠A = 18°.
Using the tangent ratio, the height of the lighthouse from the top of the cliff ≈ 161.2 meters.
<h3>What is the Tangent Ratio?</h3>
For solving a right triangle, the tangent ratio that can be applied is: tan ∅ = opposite length / adjacent length.
Find the height of the light house and the cliff using the tangent ratio:
tan 51.3 = height/980
Height of lighthouse + cliff = (tan 51.3)(980)
Find the height of the cliff only using the tangent ratio:
tan 47.3 = height/980
Height of cliff = (tan 47.3)(980)
Height of the lighthouse from the top of the cliff = (tan 51.3)(980) - (tan 47.3)(980)
Height of the lighthouse from the top of the cliff ≈ 161.2 meters.
