Answer 1

The value of SU is 36

Explanation:

Given;

• ∆STU ~ ∆SEF

So,

ST/SE = SU/SF

Here,

• ST = 39
• SF = 12
• SE = 13
• SU = ?

Let us take SU as x

Now,

ST/SE = SU/SF

39/13 = x/12

3 = x/12

Multiply 12 from both sides we get,

3 × 12 = x/12 × 12

36 = x

x = SU = 36

Thus, The value of SU is 36

ST/SE = SU/SF

39/13 = 36/12 = 3
