X: y = 5:3 and x+ y=56
Work out the value of x-y

14

Step-by-step explanation:

Given: x : y = 5: 3

Therefore, let x = 5a and y = 3a

x + y = 56

5a + 3a = 56

8a = 56

a = 56/8

a = 7

x = 5*7 = 35

y = 3*7 = 21

Therefore,

x - y = 35 - 21 = 14

answer is 67%

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
