Prove that the triangle EDF is isosceles. Give reasons for your answer.

Gekata [30.6K]

Answer:

$\triangle EDF$ is isosceles.

Step-by-step explanation:

Please have a look at the attached figure.

We are given the following things:

$\angle EDF = y$

$\text{External }\angle DFG = 90 +\dfrac{y}{2}$

Let us try to find out $\angle E$ and $\angle DFE$ . After that we will compare them.

Finding  $\angle DFE$ :

Side EG is a straight line so $\angle GFE = 180$

$\angle GFE$ is sum of internal $\angle DFE$ and external $\angle DFG$

$\angle GFE = 180 = \angle DFE + \angle DFG\\\Rightarrow 180 = \angle DFE + (90+\dfrac{y}{2})\\\Rightarrow \angle DFE = 180 - 90 - \dfrac{y}{2}\\\Rightarrow \angle DFE = 90 - \dfrac{y}{2} ....... (1)$

Finding  $\angle E$ :

Property of external angle: External angle in a triangle is equal to the sum of two opposite internal angles of a triangle.

i.e. external $\angle DFG$ = $\angle E + \angle EDF$

$\Rightarrow 90+\dfrac{y}{2} = \angle E + y\\\Rightarrow \angle E = 90+\dfrac{y}{2} -y\\\Rightarrow \angle E = 90-\dfrac{y}{2} ....... (2)$

Comparing equations (1) and (2):

It can be clearly seen that:

$\angle DFE = \angle E =90-\dfrac{y}{2}$

The two angles of $\triangle EDF$ are equal hence $\triangle EDF$ is isosceles.

Solve the following equation. Then place the correct answer in the box provided. Answer in terms of a mixed number. 7(2x + 6) =

BabaBlast [244]

Hey there! :D

7(2x+6)=1

Use the distributive property. Multiply each number by each other.

7*2x= 14x 7*6= 42

14x+42=1

Subtract 42 on both sides.

14x= -41

Divide both sides by 14.

We know that 14 goes into -41 almost three times.

14*3= 42 (there is one left over)

-2 13/14 (we just need one more part of 14)

That is the simplified number.

I hope this helps!

Richard practiced each of 3 piano solos for 5/12 hour. how long did he practice in all?

maksim [4K]

You are given Richard’s piano practice for 3 piano solos. Every piano sol he makes takes 5/12 hour. You are asked to find how long Richard is going to practice his piano solo. So we have for every 1 piano solo he makes this is equal to 5/12 hours. This can be best represented by ratio and proportion.

1 piano solo/(5/12 hour) = 3 piano solo/(number of hours)
Number of hours = 3 piano solo/ (1 piano solo/5/12 hours)
Number of hours = 5/4 hours or 1.25 hours.
