someone PLEASE help

OpenStudy (campbell_st):

1st you need to find y... the 3 angles 56 + 51 + y = 180 then use angle sum of a triangle to find x

OpenStudy (anonymous):

how do i do tht?

OpenStudy (campbell_st):

y = 180 - 56 - 51

OpenStudy (anonymous):

73

OpenStudy (campbell_st):

then all you need to do, is find the missing angle in the triangle, knowing the other 2 angles

OpenStudy (anonymous):

how?

OpenStudy (campbell_st):

same process, angle sum of a triangle is 180, so subtract the 2 angles you know.. to find x.

OpenStudy (anonymous):

@campbell_st so its 73

OpenStudy (campbell_st):

ok... you just found an angle inside the triangle... you have been given another angle inside the triangle... the 3 angles inside a triangle add to 180... you know 2 angles... so x is 180 minus the 2 angles you know

OpenStudy (anonymous):

WHAT ANGLES?

OpenStudy (anonymous):

56 and 51?
