Help please?????????????
N76 [4]

Answer:

Step-by-step explanation:

The given triangle ABC is an obtuse triangle because one of its angles it greater than 90 degrees. The sum of the angles in a triangle is 180 degrees. This means that

Angle A + Angle B + Angle C = 180 degrees

Looking at the triangle,

Angle A = 30 degrees

Angle C = 20 degrees

Therefore,

30 + angle B + 20 = 180

Angle B + 50 = 180

Subtracting 50 from the left hand side and the right hand side of the equation, it becomes

Angle B + 50 - 50 = 180 - 50

Angle B = 130 degrees
