Answer 1

question

In right angled triangle ABC, 8 cm, 15 cm and 17 cm are the lengths of AB, BC and CA respectively. Then, find sin A, cos A and tan A. 7 om PR = 25 cm and ZQ = 90° -

According to question,

According to question, Angle B =90

According to question, Angle B =90 for angleA

According to question, Angle B =90 for angleAbase(B)=8cm

perpendicular(P)=15cm

perpendicular(P)=15cm hypotensue (H)= 17cm

sinA= P/H

=15/17

cosA=B/H

=8/17

tanA=P/B

= 15/8
