PLEASE! Can someone help me find the degree of the question mark, and it's not a right angle as well. http://i.imgur.com/EUFYj.png

We see that angles 155 and x make up a straight line, so 155+x = 180

jimthompson5910 (jim_thompson5910):

solve for x

OpenStudy (anonymous):

x=25

jimthompson5910 (jim_thompson5910):

good

jimthompson5910 (jim_thompson5910):

the 3 angles in a triangle add to 180 degrees, so 25 + 60 + y = 180 solve for y

OpenStudy (anonymous):

@jim_thompson5910 y = 95

jimthompson5910 (jim_thompson5910):

good, so this means

jimthompson5910 (jim_thompson5910):

finally, you just need to solve 95+z = 180 to get the final answer

OpenStudy (anonymous):

@jim_thompson5910 Z = 85

jimthompson5910 (jim_thompson5910):

you nailed it

OpenStudy (anonymous):

Thnx!
