sum of the angles in triangle = 180
given angles = 38 and 47
unknown angle = x
therefore , 180 - (38+47) = x
180 - 85 = x
95 = x
The answer is B

sum of angles=180 for a triangle
so required angle=180-38-47 = 95 degrees

don't forget the sum of a triangle is180 so,180-38+47=95

b correct: the sum of angles is180
so 180-(38+47)= 138-85=95

b
the sum of three angles of a triangle always = 180
180-38-47 = 95

all three angles of any triangle have to add to equal 180 degrees. So subtract the two given from 180

Obtuse 36=perspective a million 40 six=perspective 2 one hundred eighty=total degress in a triangle x=lacking perspective 36+40 six+x=one hundred eighty 80 two+x=one hundred eighty -80 two -80 two ----------------- x=ninety 8 when you consider that a minimum of on of the angles is better than ninety degress, its an obtuse triangle. (obtuse means better than ninety)
