Question

Two interior angles of triangle PQR measure 27° and 79°.


What is the measure of ∠PQR?
A. 74°
B. 90°
C. 174°
D. 254°

Answer 1

srry. i'm not good at these types. but i'll get someone.

Answer 2

Anonymouse said she will help me

Answer 3

k.

Answer 4

The three internal angles of a triangle always add up to 180 deg

you know 2 of them (27 and 79) - so what is the third so that the three angles add to 180?

Answer 5

A.

Answer 6

Wait here is pricture of the triange give me two mintes to pull it up

Answer 7

Yes, what you said above me is correct. All triangles have the measure of 180 degrees. So if you have two of the measures and searching for the length of the last angle you can add the two sides that you do have up and then subtract by 180 and you will get your answer.

Answer 8

or maybe it is
B or C or D

Answer 9

IF the answer were A - would all the angles add up to 180?

Answer 10

I got A 74 because since a full triangle = to 180 I took 180-79-27=74 but the opposite of the would be 74+79+27=180. Am I correct??

Answer 11

Anonymouse is that correct

Answer 12

Sorry, @MrNood, I suck at explaining my answers.

Answer 13

If you are confident of the method, and have checked your work - then choose that answer.

Answer 14

I have another question do you mind helping so more

Answer 15

Yes, that is right.

Answer 16

I'll help you with your other questions.

Answer 17

ok thx

Answer 18

What is the measure of angle DFG, in degrees?

A. 66
B. 114
C. 156
D. 180

Answer 19

Here is the picture of the triangles

Answer 20

What do you think the answer is?

Answer 21

180-D

Answer 22

I agree because they did not ask for the measure of one angle, they asked for the entire angle, so safely assuming the answer would be D.

Answer 23

Lines r and s are parallel. Which shows accurate angle relationships?

A. ∠5 ≅ ∠4; ∠1 ≅ ∠8
B. ∠5 ≅ ∠7; ∠1 ≅ ∠7
C. ∠4 ≅ ∠6; ∠4 ≅ ∠5
D. ∠4 ≅ ∠5; ∠8 ≅ ∠2

Answer 24

A

Answer 25

Lines d and f are parallel, and lines j and k are parallel. Which angle is congruent to ∠7?

A. ∠4
B. ∠6
C. ∠11
D. ∠14

Answer 26

sorry cant help you

Answer 27

What do you think?

Answer 28

Um...................................<7 is = to <11 is c

Answer 29

I agree.

Answer 30

What is the measure of ∠P?


A. 36°
B. 43°
C. 101°
D. 180°
For this one I got c-101

Answer 31

Are there measurements for the others side or is there a picture?

Answer 32

there's a pi hold on let me post it

Answer 33

C is right.

Answer 34

ok...thank you......

Answer 35

I have more

Answer 36

Okay

Answer 37

Which set of interior angle measures can form a triangle?
A. 50°, 50°, 100°
B. 100°, 25°, 50°
C. 100°, 35°, 50°
D. 100°, 35°, 45°

Answer 38

and there is no graph or picture for this problem okay.

Answer 39

What do you think?

Answer 40

A?

Answer 41

No, A. add up to 200 and we are trying to make a triangle.

Answer 42

I did it over and I got D 100+35+45=180

Answer 43

-claps- Yes! D is right.

Answer 44

Can you help me with three more

Answer 45

Then I will be done

Answer 46

Whooah - above

What is the measure of angle DFG, in degrees?

The notation DFG means go from D to F then to G

The angle they want in the question a way back is the EXTERNAL angle.

You need to first solve the internal angle (same as before) then the external angle can be got from that
