The two triangles are similar, so the side lengths are similar:
11 * y = 121 + 11 = 132
10 * y = (5x + 10) + (10 * y)
y = 121 / 11 = 12
(10 * 11)= (5x + 10) + (10 * 11)
110 = 5x + 10 + 110
5x + 10 = 0
5x = -10
x = -10 / 5 = -2
x = -2
The amount of money Emma receives in this scenario is £35.
<h3>What is Ratio?</h3>
This is defined as a comparison of numbers that indicates their sizes in relation to each other.
Helen and Emma = 2 : 5
2 = 5
x = x+21
We then cross multiply
5x = 2 ( x+21)
5x = 2x + 42
5x - 2x = 42
3x = 42
x = 42/3 = 14
Emma received x+21
= 14+21 = £35
