Question

What is the measure of angle B?


Answer
62
32
120
31

Answer 1

31

Answer 2

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

Answer 3

x=31
so B = 62 degrees

Answer 4

answer is 31

Answer 5

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

Answer 6

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

Answer 7

x=31, 2x=62
