Question

Math help plz its desperate

Answer 1

is this geometry?

Answer 2

yes =_=

Answer 3

I know how to do this! So you should know that the sum of all angles of a triangle is 180 degrees. So you know one angle is 51, and the other is x. You have to find the angle of the third angle before x.

Answer 4

So to start off, what is the angle of a straight line?

Answer 5

Im not trying to be mean, but i fugred it out, do you mind helping me with another? ;-;

Answer 6

sure

Answer 7

ok so same thing. How many degrees is the angle with the box?

Answer 8

90

Answer 9

yes! so the angle of a line is 180 degrees and you know that a part of that straight line is 121 degrees.

180-121=59

you now know that one angle is 90, another is 59. How would you find x?

Answer 10

almost, you have the idea but 90 plus 59 is 149, not 121

Answer 11

121 is the outside angle. you have to use 59 becuz the sum of the outside and inside angle have to be 180!

Answer 12

ahhhh so like x+59=180?

Answer 13

no... so you know the total angle of a triangle is 180. one angle is 90 (right angle) and the second is 59 (cuz the outside angle is 121). you have to add up all three angles to get 180 since it is a triangle.

90+59+X=180

Answer 14

hehe i see you also use big ideas math! I use it too! What level are you in?

Answer 15

8th, grade

Answer 16

oop im in 6th doing 8th grade rn

Answer 17

anyways, what i said, does it make sense?

Answer 18

Yes, so like this?

Answer 19

x=31

Answer 20

I did it :D

Answer 21

yes!
