the external angle = sum of two opposite internal angles ie 5x-35 = 58 + 2x solve for x angle B = 2x

OpenStudy (anonymous):

x=31 so B = 62 degrees

OpenStudy (anonymous):

answer is 31

consider d unknown angle as y, so d sum of a triangle n alternate angle is 180 so 2x+y=122 n 5x+y=215 solve this linear eqn u'll get d answer 31

OpenStudy (anonymous):

sorry value of x=31 n assumed y ie b=60

OpenStudy (anonymous):

x=31, 2x=62
