Mary is standing out on the balcony of her apartment which is 40 feet above the ground and looks up at a 31° angle to see her fr
Sergio [31]

Answer:

52 feet

Step-by-step explanation:

This situation can be represented by the attached figure as in the answer area.

Let M be the location of Mary.

Let S be the location of Sue.

Distance between apartments is given as 20 feet.

Distance between ground and balcony of Mary is 40 feet.

There is a right angled \triangle MOS.

\angle OMS = 31^\circ

To find:

The distance SO + 40 feet.

We can use tangent ratio here in right angled \triangle MOS.

tan\theta = \dfrac{Perpendicular}{Base}

tan31^\circ = \dfrac{SO}{MO}\\\Rightarrow tan31^\circ = \dfrac{SO}{20}\\\Rightarrow SO=20\times 0.6\\\Rightarrow \bold{SO=12\ ft}

Height of Sue above ground = 40+12 = <em>52 feet</em>

A soccer tournament there are (16x + 30 ) boys and (5x - 12) more girls than boys. How many children are there at the tournament
Radda [10]
So here is the equation for the total amount of kids:
(16x+30)+ [(16x+30)+(5x-12)]
Boys                   Girls

This is simplified to 37x+48 in terms of x using PEMDAS.
