Question

please solve question number 4​

Answer 1

Answer:

Your answer is here :-

Step-by-step explanation:

a) 90° + x = 180° (Complementary angle )

x = 180° - 90°

x = 90°

b) 80° + 60° + 90° + x = 360° ( angle sum property of quadrilateral )

x = 360° - 80° - 60° - 90°

x = 360° - 230°

x = 130°

c) Sum of angle of Pentagon is 540° and it have 5 sides. so,

5x = 540°

x = 540°/ 5

x = 18°

d) 120° + x = 180° ( complementary angle )

x = 180° - 120°

x = 60°
