Answer:
30.1°
Step-by-step explanation:
Let A = angle of elevation
tan A = 55/95
A = arctan 55/95
= 30.1°
(Answer: 120) angle EHF = 90 degrees+30 degrees=120 angle
Answer:
1931.7N
Step-by-step explanation:
We are told in the question that :
An auto ( a car) weighs = 2500 pounds
It s inclined at n horizontal Ange of 10°
We are asked to find the force that would prevents it from rolling down the street.
Since the unit for Force = Newton or kgm/s²
Step 1
Convert Weight in pounds to kg
1 pound = 0.453592kg
2500 pounds =
2500 pounds × 0.453592kg
= 1133.981kg
Step 2
Find the force that would prevents it from rolling down the street.
Force = Mass × Acceleration due to gravity × sin θ
Acceleration due to gravity = 9.81m/s
Force = 1133.981kg × 9.81 × sin 10°
Force = 1931.7237321 N
Approximately = 1931.7N
We don't need to graph the line. All we have to do is use our slope formula.

Hello...
Area is measured by the formula A=L*W (Area = Length X Width) We know the area is 38 1/4 and the width is 4 1/2. It is easiest to convert them to decimals and solve. 38 1/4 = 38.25 and 4 1/2= 4.5 . so, 38.25 = 4.5 * W
To solve for Width, we need to isolate it by getting 4.5 on the other side. To do this, we divide by 4.5 on both sides of the equals sign. this will give us W=8.5 or Width = 8 1/2 meters.
