OpenStudy (anonymous):

y = 90 - 55 z = 9 - y x = 90 - z

OpenStudy (anonymous):

cuz they are all 90 degrees

OpenStudy (anonymous):

z = 90 - y

OpenStudy (anonymous):

i still dont get it

OpenStudy (anonymous):

could you explain to me lol sorry

OpenStudy (anonymous):

55 and y are complementary angles, that means they add up to 90 degrees so 55 + y = 90 and if we subtract 55 from both sides we have the value of y

OpenStudy (anonymous):

but how did you get z and x

OpenStudy (anonymous):

z+y=90 z+x=90 do the same, cuz remeber we know wat is y, and with y we can find z and with z we can find x
