Answer:
-39/4 decimal form is -9.75 mixed number form is -9 3/4
Step-by-step explanation:
A) If you subtract 8 ft from each side, the overall perimeter would be less 32 feet.
The angle of elevation is 18. 43 degrees
<h3>What is angle of elevation?</h3>
Angle of elevation can be described as an angle formed between a horizontal line and the line of sight above the line.
From the information given, we have that;
- Length of opposite side = 1 meter
- Length of adjacent side = 3 meters
- Angle of elevation = θ
Using the tangent identity, we have;
tan θ = opposite/ adjacent
tan θ = 1/ 3
Divide the values
tan θ =0. 3333
Find the tan inverse of the value to determine θ
θ = tan^-1(0. 3333)
θ = 18. 43 degrees
Hence, the value is 18. 43 degrees
