Answer 1

Answer:

let us take 1x , 2x , 3x , 4x

1x+2x+3x+4x=360°

10x=360°

x=360°÷10

x=36°

1.❇

Let the angle A = 1x

Let the angle B = 2x

Let the angle C = 3x

Let the angle D = 4x

Sum of the angles of a quadrilateral = 360°

= 1x + 2x + 3x + 4x = 360°

= 10x = 360°

= x = $\frac {360°}{10}$

= x = 36

______________________________________

Measure of the angles

= A = 1x

= 1 × 36

= 36

= B = 2x

= 2 × 36

= 72

= C = 3x

= 3 × 36

= 108

= D = 4x

= 4 × 36

= 144
