Question

Can someone help me with this thankyou

Answer 1

Answer:

x = 20

y = 20

Step-by-step explanation:

Remark

This is a proportional question. One triangle is inside the other. I've used the larger to the smaller.

Equation

x/16 = 15 / 12

Solution for x

12x = 15 * 16

Divide by 12

x = 15 * (16/12)

x = 15 * (4/3)

x = 60 / 3

x = 20

==========================

Solution for y

(y + 5)  / y = 15/12   Reduce the right

(y + 5) / y = 5/4       Cross Multiply

4(y+5) = 5y             Remove the brackets

4y + 20 = 5y           Subtract 4y from both sides

20 = 5y - 4y

20 = y
