Answer 2

Answer:

i 64/289

ii 225/289

Step-by-step explanation:

cot theta = 8/15

which means base / perpendicular

by Pythagoras theorem,

H^2= 64 + 225

H^2=289

H=17

Now,

Sin theta = p/h= 15/17 and cos theta= b/h = 8/17

(1-Sino)(1+Sino)= (1-Sino)^2= Cos^2theta

(8/17)^2=64/289

ii,

(1+Cos0)(1-Cos0)=(1-Cos0)^2=Sin^2theta

(15/17)^2= 225/289
