Step-by-step explanation:

Question. 1 : In ∆ ABC, right-angled at B, AB = 24 cm, BC = 7 cm. Determine:

(i) sin A, cos A

(ii) sin C, cos C

Question 2: If Sin A = 3/4, Calculate cos A and tan A.

Question.3: If ∠A and ∠B are acute angles such that cos A = cos B, then show that ∠ A = ∠ B.

Question 4: If 3 cot A = 4, check whether (1-tan2A)/(1+tan2A) = cos2 A – sin2 A or not.

Question 5: In triangle PQR, right-angled at Q, PR + QR = 25 cm and PQ = 5 cm. Determine the values of sin P, cos P and tan P.

Question 6 :SinA+Sin2A=1, then find the value of (cos2A+cos4A).

HOPE THIS HELPS YOU
