Ok the ladder and the ground will make a right triangle/right angle. This is because the ground is flat, the wall is straight and only the ladder is leaning/slanted. I hope this helps.
Answer:$642
Step-by-step explanation:
Solution:
First, calculate the amount of sales tax by multiply the percent tax times the total cost:
0.07×600 =42
Next, add the amount of tax to the price of the computer:
600+42=642
From the reference of the 18 degree angle, 'h' is the opposite side and 100 is the adjacent side.
The trig ratio which uses both the opposite and adjacent sides is the tangent.
tan(18) = opp/adj = h/100
Trig equation:
tan(18) = h/100
Answer:
12π ≈ 37.7
Step-by-step explanation:
A = π*r² - π*r²/4
A = 3πr²/4
r = 4
A = 3π(4)²/4
A = 12π ≈ 37.7
