Answer:

Δ ABC \sim Δ DEF

Step-by-step explanation:

Given:

\frac{AB}{DE} = \frac{AC}{DF}= \frac{BC}{EF}

W need to Prove Δ ABC \sim Δ DEF

Solution:

Statement:                                                  Reason

\frac{AB}{DE} = \frac{AC}{DF}= \frac{BC}{EF}                    a) Given

"While Constructing both the triangle the lines were made parallel."

DE ║ AB                            c) Construction of Δ DEF on to Δ ABC

" When the Lines are parallel then their corresponding angles are equal in measure."

∠A ≅ ∠ EDF and ∠C ≅ ∠ EFD d) Corresponding Angles of parallel lines

Now By AA similarity theorem which states that;

"When 2 angles of one triangle are congruent to corresponding 2 angles of another triangle then 2 triangles are said to be similar."

Δ ABC \sim Δ DEF        b) By AA Similarity theorem.

diamong [38]

Answer:

11 people will get both the prizes.

Step-by-step explanation:

In this question we need to find common integral multiples of 5 and 7 under 400. As you can see in the figure 35th person is the first one to get both ipod and psp. The LCM (least common multiple) of 5 and 7 which is 35 (!!! <em>I hope you know how to LCM of two integers </em>).

Therefore the integral multiples of 35 will be same as the common multiples of 5 and 7. So, figuring out the number of integral multiples of 35 under 400 will give the answer.

To do that divide the number 400 with 35. On performing the division the quotient will be 11 and the remainder will be 15.

Therefore 11 persons out of 400 will get both the prizes.

Similarly if you want to find the number of person getting ipod then divide 400 with 5. The quotient will be 80. ∴ 80 people will get ipod.

And for psp, divide 400 with 7. The quotient will be 57. ∴ 57 people will get psp.

In these divisions, consider just the quotient, here remainder is of no use.

Tip: decimal to percentage is easy. 0.78 would be 78%. percentage would be vice versa 39% is 0.39. decimal or percentage to fraction is easy aswell, make the number out of 100, meaning 39% would be 39/100

\pink{ 5.37}

  • <u>To visualize 5.3</u><u>7</u><u> more accurately, divide line segment between 5.37 and 5.38 in ten equal parts. 5.3</u><u>7</u><u> lies between 5.377 and 5.378.</u>

  • <u>Again </u><u>use </u><u>divide</u><u> above portion between 5.377 and 5.378 into 10 equal parts, which shows 5.3</u><u>7</u><u> is located closer to 5.3778 than to 5.3777</u><u> </u><u>so </u><u>we </u><u>can </u><u>get </u><u>the </u><u>answer</u>

<h2><u>hope</u><u> it</u><u> helps</u></h2>
