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
Step-by-step explanation:
midpoint
(x,y)
x point = (6+9)/2 = 7.5
y point = (4+1)/2 = 2.5
midpoint of endpoints (6,4) and (9,1)
is (7.5,2.5)
