5 months ago|dw:1540230494465:dw| okay so what is x?

5 months ago90

5 months agoYup.

5 months ago|dw:1540230731669:dw| Now. You know that all angles inside a triangle add up to 180 degrees right? And based on the image, the top 2 angles are the same, since a bisector divides it into 2 equal parts. If all the angles add up to 180, then 90 + 47 + y = 180. Can you find y?

5 months agoi think so

5 months agowhat else ?

5 months agoi can figure out the y

5 months agowell 90 + 47 + y = 180 137 + y = 180 right? y = 180 - 137

5 months agounderstand so far?
