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.
good luck learning!
