Question

the angles of a quadrilatiral are in the ratio 1;2;3;4;.what are the measure of 4 angles?

Answer 1

Answer:

144

Step-by-step explanation:

$1x \: 2x \: 3x \: and \: 4x \\ sum \: of \: measure \: of \: angles \: of \: quadrilateral = 360 \\ 1x + 2x + 3x + 4x = 360 \\ 10x = 360 \\ x = 36 \\ \\ 4x = 4 \times 36 = 144 \\ therefore \: fourth \: angle \: is \: 144$
