Answer 2

Answer is

X= 18

Step by step explanation

Acc to question it is saying that one angle is of 45° other than 90° ok and its perpendicular is of 18 m

Now taking the 45°

Tan 45°=P/Q

AS YOU KNOW TAN 45°=1

AND IN THIS LET THE BASE OF THE TRIANGLE WHICH IS THE PERPENDICULAR FOR THAT ANGLE LET IT BE X

AND THE BASE BE 18 WHICH IS GIVEN

JUST PUT THE VALUES NOW

TAN 45= X/18

1=x/18
