52). 5x=45 Divide each side of the equation by 5.

53). -3x = 12 Divide each side by -3.

54). x/4 = 10    Multiply each side by 4 .

55). x/3 = -8    Multiply each side by 3 .

1). x -10 = 12 . Add 10 to each side.

3). x + 8 = 16    Subtract 8 from each side.

5). 5 + x = 6 Subtract 5 from each side.

7). x - 4 = 9    Add 4 to each side.

Thank you for the 5 points. The crust and warm water are delicious.

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 $\angle DFG$

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