"A 20-foot ladder leans against the side of a house. The bottom of the ladder is 6 feet away from the house. What is the measure
of the angle formed by the ladder and the ground?" How do I answer this?
1 answer:
Answer:
Value of θ [Angle of elevation] = 72.54°
Step-by-step explanation:
Given;
Length of foot ladder = 20 feet
Distance of foot from house (Base) = 6 feet
Find:
Angle of elevation
Computation:
Using trigonometry functions
Cos θ = Base / Hypotenuse
Cos θ = Distance of foot from house (Base) / Length of foot ladder
Cos θ = 6 / 20
Cos θ = 0.3
Cos θ = Cos 72.54
Value of θ [Angle of elevation] = 72.54°

Answer:
Given : PQ = RQ
to find : angle B
- PQ = RQ
- Angle B = angle QRP ( angle opposite to equal side are equal). ...(1)
- angle QRP + 140° = 180° ( linear pair)
- angle QRP = 180° - 140°
- angle QRP = 40°
- from equation (1)
- Angle B = angle QRP = 40°

Step-by-step explanation:
20 × 400 = 8000
8000 - 7200 = 800
therefore the % mark up is 10%, because 10% of 8000 is 800.
800 + 7200 = 8000
Dividing two negatives equals a positive:
(-63) / (-9) = 7
