Answer 1

What do the degrees of a triangle add up to?

Answer 2

please help

Answer 3

86

Answer 4

can you help @EmogirlAtEmoooocow

Answer 5

is there a answer choice

Answer 6

no it is type it in

Answer 7

Oh just add the 2 numbers then u get the answer

Answer 8

The angles of a triangle should add up to 180. So, you have \[52 + 34 + x = 180\] Solve for x.

Answer 9

is it 84 or 86

Answer 10

Neither. Add 52 and 34. Then subtract 180.

Answer 11

94

Answer 12

right?

Answer 13

Bingo.

Answer 14

oh thanks can you help with one more

Answer 15

Answer 17

Yeah of course!

Answer 18

This is very similar to the previous problem.

If all angles of a triangle add up to 180. What are the angles of the triangle you have in question?

Answer 19

how do i solve this one

Answer 20

44 and 66

Answer 21

66+44+x (angle 3) = 180

Solve for x.

x=180-66-44

Answer 22

so it should be 170 but the angle that they are asking for is an acute as you can see in the picture

Answer 23

You got it, keep going. To solve the angle we had before we just added the angles we DID know and subtract 180. Same thing in this one.

Answer 24

70

Answer 25

the answer is 70

Answer 26

No, you're subtracting 66 and 44 from 180.

Answer 27

i got an 80 thanks so much

Answer 28

Exactly!

Answer 29

No problem. Best of luck and remember that about triangles and you'll be able to find the unknown.
