Question

ABCD is a cyclic quadrilateral which angle A =80 and angle B= 75 then angle D =?​

Answer 1

Answer:

Step-by-step explanation:

THE SUM OF ALL ANGLES IN A QUADRILATERAL IS EQUAL TO 360°

A + B + C + D = 360°

80° + 75° + 100° + x = 360°

255° + x = 360°

x = 360° - 255°

x = 105°

THERE FORE,

ANGLE D IS EQUAL TO

105°

Answer 2

The answer is 105 degrees.
