Question

can u help me idk how to answer this

Answer 1

First Figure

Interior unknown angle = 180-58 = 122 (Linear Pair)

Sum of all angles in a quadrilateral is 360°

=> 87+94+122+x = 360

=> x = 57°

Second Figure

Sum of all angles is 360° (Complete Angle)

136+74+e+97 = 360

=> e = 53°

Third Figure

Sum of all angles is 180° (Angles on a straight line)

62+27+45+b = 180

=> b = 46°

Fourth Figure

Sum of all angles of a triangle is 180°

43+56+d = 180

=> d = 81°
