1. A trapezoid has an area of 91 m2. The height of the trapezoid is 7 m and the measure of one base is twice the height. What is
Lynna [10]
The area of the trapezoid is given by:
 A = (1/2) * (b1 + b2) * (h)
 Where,
 b1, b2: bases of the trapezoid
 h: height
 Substituting values we have:
 91 = (1/2) * ((2 * 7) + b2) * (7)
 Rewriting we have:
 91 = (1/2) * (14 + b2) * (7)
 (2/7) * 91 = 14 + b2
 b2 = (2/7) * 91 - 14
 b2 = 12 m
 Answer:
 
The measure of the other base of the trapezoid is:
 
b2 = 12 m

A person stands 15 ft from an elephant. Determine how tall the elephant is in feet, the given diagram.
Leno4ka [110]

Answer:

The height of the elephant is \dfrac{15}{\sqrt3}\ ft.      

Step-by-step explanation:

It is given that,

Distance between a person and an elephant is 15 ft

The angle of elevation of the elephant is 30 degrees.

We need to find the height of the elephant. For this let us consider that height is h. So,

\tan\theta=\dfrac{P}{B}\\\\\tan(30)=\dfrac{h}{15}\\\\h=15\times \tan(30)\\\\h=\dfrac{15}{\sqrt3}\ ft

So, the height of the elephant is \dfrac{15}{\sqrt3}\ ft.
