Answer 2

Step-by-step explanation:

(i) sin(x + y) = sin x cos y + cos x sin y = (15/17) x (12/13) + (8/17) x (5/13) = (180/221) + (40/221) = 220/221 (ii) cos(x - y) = cos x cosRead more on Sarthaks.com - https://www.sarthaks.com/910237/if-sin-x-15-17-and-cos-y-12-13-0-x-2-0-y-2-find-the-value-of-i-sin-x-y-ii-cos-x-y-iii-tan-x-y?show=910261#a910261
