<h2>Hello!</h2>

The answer is D.  1.5 hours

<h2>Why?</h2>

First we need to calculate the speed using the following formula and the given information:

x_{f}=x_{o}+v*t\\x_{f}-x_{o}=v*t\\\\d=v*t

Where:

d=distance\\x_{f}=FinalPoint\\x_{o}=InitialPoint\\v=velocity/speed\\t=time

By substiting we have:

v=\frac{distance}{time}=\frac{221.05miles}{4hours}=55.26\frac{miles}{hour}

So, to calculate the time she took to cover the last distance, we need to use the calculated speed:

distance=v*t\\t=\frac{distance}{speed}\\t=\frac{83miles}{55.26\frac{miles}{hour}}=1.50hours

The time she took to cover the last distance is D.  1.5 hours

Have a nice day!

Which theorem would you use to prove ABE ~ DCE?
Pachacha [2.7K]
Answer: Choice C) AA similarity

------------------------------------------------------------------------------
------------------------------------------------------------------------------

We are given that angle ABE = angle ECD since they are both right angles (square marker)

Angle AEB = angle CED as they are vertical angles

we have two pairs of congruent angles, leading us to be able to use the AA (angle angle) similarity theorem

Please help I don’t know how to solve these... can anyone explain? I’m desperate
Elenna [48]

Answer:

1.) 16.5

2.) 24.2 ft

3.) 10.8 ft

Step-by-step explanation:

1.) So first you need to use Heron's formula

S = (A + B + C)/2

So

S = (17 + 17 + 8)/2

S = 21

Now

Area  = \sqrt{S(S - A)(S-B)(S-C)}

So

\sqrt{21(21-17)(21-17)(21-8)}

So the Area is equal to 66.1

Now to find the height we use the Area of the triangle formula

A = 1/2 B*H

66.1 = 1/2(8) * H

66.1 = 4H

H = 16.525

So the height of the triangle is 16.5 units tall

2.) For this question you just use the Pythagorean theorem.

a² + b² = c²

So 22² + 8² = c²

484 + 64 = c²

548 = c²

\sqrt{584} = c

c = 24.1660919472 ft

So the length of the wire is 24.2 ft long

3.) Again this is the Pythagorean theorem.

a² + b² = c²

So 10² + 4² = c²

100 + 16 = c²

116 = c²

\sqrt{116} = c

c = 10.7703296143 ft

So the length of the banner is 10.8 ft long
