Answer
As per the statement:
Height of the building(h)= 30 feet
Angle of elevation 
= 41°
We have to find the distance of observer from the base of the building.
Using tangent ratio:
You can see the diagram as shown below.
Opposite side = height of the building = 30 feet.
Adjacent side = distance of observer from the base of the building = x (let)
Then;
0.86928673781 = 
By cross multiply we have;
Divide by 0.86928673781 both sides we get;
x = 34.51 m
Therefore, the distance of observer from the base of the building is 34.51 m
Answer:
Sin(theta) = 3/5
Step-by-step explanation:
Remark
The Sin(theta) = opposite / hypotenuse
The opposite side is not defining the angle. The hypotenuse is the longest side of a right triangle.
In this case the opposite is 3
The hypotenuse = 5
Answer: Sin(theta) = 3/5
Answer:
x = -3
Step-by-step explanation:
First, we want to sub in the numbers then isolate the variable. We subtract 4 from both sides. That gives us 13 - 4 = -3x which equals 9 = -3x. Now we divide both sides by -3. So x equals -3. I hope this helps! Please make me the brainliest! Thanks!
No. 1/2 equals 5/10, so 3/10 is actually less than 5/10.
