Question

An angle of sinA is to cosineA is 8:15.find their actual values.

Answer 1

sina/cosA=8/15 tanA=8/15 We know that 1+tan^2A=sec^2A Putting value of tanA 1+(8/15)^2=sec^2A sec^2A=1+64/225 Hence SecA=17/15 That means cosa=15/17 sinA=(1-cos^2A)^1/2 Therfore sinA=(1-225/289)^1/2 sinA=8/17 Hope you understood.

Answer 2

Answer:

Step-by-step explanation:sinA/cosA=8/15

so,tanA=8/15

p/b=8/15,p=8 and b=15

h^2=15^2+8^2

h=17
