Question

a quadrilateral has three acute angles measuring 55 degree each find the fourth angle​

Answer 1

Step-by-step explanation:

sum of three acute Angles of quadrilateral

= 3 × 55 = 165°

let fourth angle be 'x° '

sum of all 4 Angles of quadrilateral

= 360°

165° + x = 360°

x = 195°

Fourth angle = 195° Ans.

Answer 2

Step-by-step explanation:

Let the fourth angle be x

A. T. Q.

=>55°+55°+55°+x =360°

=> 165° +x =360°

=> x=360° - 165°

.°. x=195° ANSWER
