The two triangles in the diagram are similar. There are two possible values of x.
Work out each of these values.
State both assumptions* you make in your working.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

60: 45 =12: 9 =4: 3 so the answer is 4: 3

y=20x
