Answer:

x = 8 ; y = 8√2

Step-by-step explanation:

In the given figure, two base angles are equal.

In an isosceles triangle, the sides opposite to the equal angles are equal.

∴ x= 8

The triangle is also right angled.

Using Pythagoras theorem,

hypotenuse² = base² + perpendicular²

y² = 8² + x² = 8² + 8² = 128

y = √128 = 8√2

∴ x = 8 ; y = 8√2

Find two numbers if their difference is 16 and their ratio is 5:7.
myrzilka [38]

Let us say that the numbers are x and y. The given clues are:

1. x – y = 16         (so x is the larger number)

2. y / x = 5 / 7

 

rewriting eqtn 2 in terms of y:

y = (5/7) x

 

combining 1 and 2:

x – (5/7) x = 16

(2/7) x = 16

x = 56

 

y = (5/7) x = 40

 

So the two numbers are 56 and 40.
