Question

Consider right angle triangle ABC such that the angle BAC =450; angle BCA=900. Further, the length of side AC=8. What is the length of side BC?

Answer 1

now we know sum of triangle is 180°

BAC=45°

BCA=90°

ABC=45°

SO NOW IT IS GIVEN THAT AC=8 WHICH REPRESENTS ANGLE (ABC)

SO NOW BAC=IS ALSO REPRESENT BC=8

AS THE ANGLES A:B:C=45:45:90

=1:1:2

SO BC:AC:AB=1:1:2

SO NOW BC=1(8)=8

AC=1(8)=8

AB=2(8)=16
