What grade is this?

OpenStudy (anonymous):

11th

OpenStudy (anonymous):

im not understanding, plugging them in doesn't get me anywhere

OpenStudy (anonymous):

For the second figure, K is equal to 70

OpenStudy (anonymous):

you got the first one?

OpenStudy (anonymous):

Tip: Every Triangle equals 180 degrees

OpenStudy (anonymous):

|dw:1411954074485:dw|

OpenStudy (anonymous):

No @satellite73 , I didn't get an answer for the first one

OpenStudy (anonymous):

But I know it's dealing with geometry but I forgot how to do it

OpenStudy (anonymous):

hen calculating do I include the number not in the triangle?

OpenStudy (anonymous):

No you just add the numbers in side the triangle. Then subtract from 180

OpenStudy (anonymous):

Like the third figure would be k = 80

OpenStudy (anonymous):

So would 7 be 85??

OpenStudy (anonymous):

7? Do you mean 6?

OpenStudy (anonymous):

I got it! For the first question, the answer is 59. X equals 59 :)

OpenStudy (anonymous):

Give me a second, and I will have all the answers to your questions. And a explanation

OpenStudy (anonymous):

Ok, I remembered that Every straight line equals 180, just like a triangle.

OpenStudy (anonymous):

For the first figure, 180-134 = 46 46+75 = 121 180-121 = 59 X = 59

OpenStudy (anonymous):

For the second figure, 52+58 = 110 180-110 = 70 K= 70 And yes another way to do this was to : 180-110 =70

OpenStudy (anonymous):

For the third figure, 68+32 = 100 180-100 = 80 K= 80

OpenStudy (anonymous):

For the fourth figure, 53+42 = 96 180-96 = 85 X = 85 I think this was the one you did

OpenStudy (anonymous):

For the fifth figure, 180-139 = 41 42+41 = 83 180-83 = 97 X = 97

OpenStudy (anonymous):

For the sixth figure, 114+47 = 161 180-161 = 19 X = 19

@annon1123 I'm done :)
