The engineer's distance from the building, the building's height and the engineer's line of sight form a right angle triangle.
Thus, we apply:
tan∅ = height/base
base = 250/tan(46)
base = 241.4 feet
So 241 feet
Answer:
Step-by-step explanation:
truncated means when its rounded up from the lower bound and upper bounds meaning lower bound=15.4 and upper bound=15.5

Answer:</h2>
The simplified form of the given polynomial equation is:
<h2>
Step-by-step explanation:</h2>
We are asked to simplify the given polynomial expression in terms of the variable x.
The algebraic expression is given as:
On taking out the terms from both the brackets the sign of the terms of the second bracket gets interchanged as there is a negative sign preceding it.
Hence, we get the expression as:
Now on combining the like terms we get:
Answer:
area of shaded portion=56 - 1/2 ×3×4=56-6= 50 yd^2
Y = mx + b
y = - 1/2x - 9/2
