Are the triangles PQR and RST similar why or why not?

Are The Triangles PQR And RST Similar Why Or Why Not?

Answers

Answer 1

Answer: The triangles are similar

======================================================

Explanation:

The square markers show that

angle RPQ = angle RST = 90 degrees

So that's one pair of congruent angles. Another pair of congruent angles is what you see in the diagram below. The angles marked in red are congruent alternate interior angles. Alternate interior angles are congruent when we have parallel lines like this.

Since we have two pairs of congruent angles, we can use the AA (angle angle) similarity theorem to prove the triangles congruent.

Are The Triangles PQR And RST Similar Why Or Why Not?
Answer 2

Answer:

Triangle PQR and RST are both right triangles but they do not share the same  side lengths. They also share the same point R, so I would say that they are similar only because they are both right triangles.

You hang two strings of decorative lights. Strand 1: changes between red and blue every 15 seconds. Strand 2: changes between green and gold every 18 seconds. Both strands just changed color. After how many seconds will the strands change color at the same time again?

Answers

Answer:

The strands change color at the same time again after 90 seconds

Step-by-step explanation:

We are told:

Strand 1: changes between red and blue every 15 seconds.

Strand 2: changes between green and gold every 18 seconds.

To solve for this question, we use the LCM method.

Step 1

List multiples of each number until the first common multiple is found.

Multiples of 15:

15, 30, 45, 60, 75, 90, 105, 120

Multiples of 18:

18, 36, 54, 72, 90, 108, 126

Therefore,

LCM(15, 18) = 90

The first common multiple is 90, and this is the lowest common multiple.

Therefore, the strands will change color at the same time again after 90 seconds.

Step-by-step explanation:

A ball thrown straight up in the air travels 90 inches in the first tenth of a second. In the next tenth of a second the ball travels 85 inches. After each additional tenth of a second, the ball travels 5 inches less than it did during the preceding tenth of a second. How long will it take before the ball starts coming back down? What is the total distance that the ball has traveled once it reaches its maximum height?

Answers

Answer:

855

Step-by-step explanation:

1.9 seconds is 19 tenths, so that means we add using the information given, which is that the ball travels 5 fewer inches every tenth of a second:

Time | Inches traveled

0.1     | 90

0.2    | 85

0.3    | 80

0.4    | 75

0.5    | 70

0.6    | 65

0.7    | 60

0.8    | 55

0.9    | 50

1.0     | 45

1.1      | 40

1.2     | 35

1.3     | 30

1.4     | 25

1.5     | 20

1.6     | 15

1.7     | 10

1.8     | 5

1.9     | 0

90+85+80+75+70+65+60+55+50+45+40+35+30+25+20+15+10+5+0=855

Horizontal lines e and f are intersected by lines a and b. At the intersection of lines a and e, the uppercase left angle is 75 degrees. At the intersection of lines b and e, the uppercase right angle is 115 degrees. At the intersection of lines a and f, the bottom right angle is 75 degrees.

Which lines are parallel? Justify your answer.


Lines a and b are parallel because their alternate exterior angles are congruent.

Lines a and b are parallel because their same side exterior angles are supplementary.

Lines e and f are parallel because their alternate exterior angles are congruent.

Lines e and f are parallel because their same side exterior angles are congruent.

Answers

Lines e and f are parallel because their alternate exterior angle is congruent. Option C is correct.

Find the diagram attached;

The point where two lines meet is known as an angle.

From the given diagram, we can see that the angle of 75 degrees is at the top left corner is similar to the 75 degrees down right.

Hence we can conclude that lines e and f are parallel because their alternate exterior angle is congruent.
