Question

1)Two numbers are in the rotio 10:11 their sum is168 . Find the numbers .
2) The Angle of a quadrilateral are in the ratio 1:2:3:4. If the sum of the angles of a quadrilateral is 360° Find the measure of each angel
please Solve it ​

Answer 1

Answer:

1) 80 : 88

2) 36 : 72 : 108 : 144

Step-by-step explanation:

1) Let's say we have 10x : 11x. We are told 10x + 11x = 21x = 168. Therefore x = 168/21 = 8. So the numbers of our ratio are -

10x : 11x = 80 : 88.

2) let's say we have the ratio 1x:2x:3x:4x for the angles of the quadrilateral. we have been told (and we know it too) that 1x + 2x + 3x+ 4x = 10x = 360. So x = 36. Now finding out the measure of the angles in easy -

1x : 2x : 3x : 4x = 36 : 72 : 108 : 144.
