Shouldn’t it be the figures are similar? theyre the same size, along with the same measure of angles.
Hundreds tens and ones 1 and 1 and 8
The question is incomplete, but if we assume that you mean AD = TD , we have :
AD = TD ===》 5x + 3 = x + 27
===》 4x = 24
===》 x = 6
_________________________________
AD = 5 × ( 6 ) + 3
AD = 30 + 3
AD = 33
Efficiency = (output)/(input).
This could also be written as
efficiency= output/(output+losses)
or
eff=(input-losses)/input
