Question

if three angles of a quadrilateral are 95°,80° and 75° then the remaining fourth angle would be

options
a) 110°
b) 55°
c) 170°
d) 0°​

Answer 1

Answer:

A) 110

Step-by-step explanation:

Sum of all angles of a quadrilateral = 360°

95°+80°+75°+x = 360°

250°+x = 360°

x = 360° - 250°

x = 110°
