Question

I have a question and idk how to post a pic so. Im doing math and it shows me the picture of a triangle and asks find the measure of <1 which is on the top corner of the tri. The left corner is 70 degrees. then the triangle has a line coming out of the it and on that line it says 135 degrees. Im confused on why it's outside the triangle. What's it mean?

Answer 4

ok i will give u the pic now

Answer 5

alright

Answer 6

thanks

Answer 7

ok by the remote exterior angle theorem, the angle of 70 degrees and angle 1 add up to the angle outside the triangle (the 135 degree angle)

Answer 8

so if angle 1 was x degrees, then

70+x = 135

Answer 9

solving for x gives you x = ???

Answer 10

ohh

Answer 11

65 is x

Answer 12

good

Answer 13

thank u! was pretty easy
