In PQR, PQ = 17.4 M And PR = 7.6 M. K Lies On QR Such That PKQ = 137 . Find (i) QPR (ii) The Length Of

Answers

Answer 1

Answer:

here:given

PQ=17.4m

PR=7.6m

QR=?

NOW:QR^2=PQ^2-PR^2

QR=[(17.4)^2-(7.6)^2]^1/2

QR=[302.76-57.76]^1/2

QR=15.65

now: in tringle PKR

ANGLE PKR=43 DEGREE            [180-137] IN TRINGLE ALL SIDES SUM 180]

tan(43)=PR/KR

Tan(43)=7.6/KR

KR=7.6/0.932

KR=8.15

NOW:QK=QR-KR

QK=15.65-8.15

QK=7.5

Answer:

10 degrees

Step-by-step explanation:

5x + 10 = 6x (because corresponding angles are equal)

6x = 10

x = 10/6

x = 5/3

6 x 5/3 = 10 degrees

Those are corresponding angles so they are congruent: 6x=5x+10

what is the value of x in the figure shown?

Answers

Answer:

x=66

Step-by-step explanation:

Hey There

So if you didn't know the exterior angle is equal to the sum of two opposite interior angles (38 and x)

so to find x we subtract 38 from 180

104-38=66

so x = 66

Answer:

52 degrees.

Step-by-step explanation:

When you look above you see 104, so divide this by 2 and get 52.

Answers

b, c and d would be the answer

Answer:

For the first one, C is the correct answer.

For the second one, C, B, and D are correct.

Step-by-step explanation:

Hi,

For the first one, you know y = x + 3 so you can just plug that into the second equation. Here's what I mean...

3x + y = 19

Plug in x + 3 for y since you know y = x + 3...

3x + (x + 3) = 19

Solve...

4x + 3 = 19

Subtract 3 on both sides...

4x = 16

Divide by 4 on both sides...

x = 4

Now, plug in 4 in the first equation.

y = x + 3

We know x = 4...

y = 4 + 3

y = 7

We know the solution is (4,7)

For the second one...

Since the two lines never intersect (cross) then there is no solution. They are parallel to each other (meaning they're going in the same direction just don't cross) and any system that doesn't have a solution will almost always have the same slope.

Hope this helps. Let me know if you have any questions :)

Answer:

42 students; (28 students); 70 students(60%); 40%; (100%)

Step-by-step explanation:

The percentages total 100%, so the missing percentage is

  100% - 60% = 40%

The numbers on the number lines are proportional, so now you can write ...

  ?/100% = 28/40% . . . . . . ? total students

Multiplying by 100% gives ...

 ? = 28/0.4 = 70 . . . . . total students

Then the 60% portion of students can be found two ways:

  60% × 70 = 42 students . . . . 60% of students

  70 -28 = 42 students

4Should more money be put into athletic programs or music programs at school? Sample is chosen from students in the band program.

5What is your favorite vacation destination? Sample is chosen by asking every student in the class.

Answers

Answer:

1 is biased, 2 isn't, 3 is biased, 4 isnt

Step-by-step explanation:

If you ask a question to people in a group who are already clearly for a certain topic then it is biased. For survey to not be biased, the people need to be chosen at random. Ask students what their favorite class is, or ask flight attendants where their favorite destination to travel to is. Dont use a group who has any relation to the survey at hand. Asking band students about funding for band is biased, as well as asking people who are at a SOCCER GAME what their favorite sport is.

In ΔGHI, the measure of ∠I=90°, GH = 96 feet, and IG = 25 feet. Find the measure of ∠H to the nearest tenth of a degree.

Answers

Answer:

15.1°

Step-by-step explanation:

In ΔGHI, the measure of ∠I=90°, GH = 96 feet, and IG = 25 feet. Find the measure of ∠H to the nearest tenth of a degree.

We solve using sine rule

GH/sin I = lG/ sin H

96/sin 90 = 25/sin H

Cross Multiply

sin 90 × 25 = sin H × 96

sin H => sin 90 × 25/96

H => arc sin( sin 90 × 25/96)

H => 15.09479°

Approximately ∠H = 15.1°
