Answer:
3.08
Step-by-step explanation:
you are looking for the hypotenuse, and have adjacent. So, use COS.
cos(73)=0.9/x
simplified 0.9/cos(73)
calculate.
Both terms have a

in common, so we can pull it out. The factored form will be

times whatever is left after pulling it out.
In the first term, we will have just 8 left since everything else in the term is factored out.
The second term has a

left. Notice that both of these terms no longer have a negative sign since the negative was factored out.
The answer is
Answer:
b
Step-by-step explanation:
64 = 2x^2
32 = x^2
x = 4√2
ans is b
Answer: the height of the building is 40ft
Step-by-step explanation:
Looking at the right angle triangle formed,
With angle P as the reference angle, the length shadow of the building on ground represents the adjacent side of the right angle triangle.
The height of the building represents the opposite side of the right angle triangle.
a) to determine the height of the building, x, we would apply the tangent trigonometric ratio which is expressed as
Tan θ, = opposite side/adjacent side. Therefore, the equation becomes
Tan P = x/50
b) 0.8 = x/50
x = 50 × 0.8
x = 40 ft
