Answer 1

let the ratio BX and the ratio are 5 is to 12 and 13 x we know that three angles of a triangle is 180 degree then 5 x + 12 x + 13 x is equal to 180 30 x is equal to 180 x is equal to 180 upon thirty is equal to six then the ratio of 5 x is equal to 5 into 6 is equal to 30 12 x is equal to 12 into 6 is is equal is to72 and 13 x is equal to 13 into 6 is equal to 78
