Question

In triangle ABC, right-angled at B, if tan A = ଵ

√ଷ

, find the value of:

(i) sin A cos C + cos A sin C

(ii) cos A cos C – sin A sin C​

Answer 1

Step-by-step explanation:

GIVEN

tan A =1/√3

tan A =P/B

so P=1

B=√3

H=?

first we find H, by pyathagorus

P means perpendicular

B means base

H means hypotenus

in this question some are sin C and sin A and

some are cos C and cos A

so we solve it to see figure angle c and angle a
