Question

In ∆XYZ, ∠X=90°, if tanX=1/√3and tanY=√3, find the value of sinx.cosy+cox x.siny

Answer 1

Answer:

n the right angled ∆XYZ, ∠XYZ = 90° and a, b, c are the lengths of the sides as shown in the ... (i) sin X (ii) tan Z (iii) cos X (iv) tan X. ... Find the remaining two ratios in the column and complete the table. sin θ, 1161, 12, 35. cos θ, 3537, 1√3. tan θ, 1, 2120, 815, 12√2 ... sinY=XZYZ=817cosY=XYYZ=1517tanY=XZXY=815

Step-by-step explanation:

Answer 2

Answer:

sinX.cosYcosX.sinY=in(60+30)

take X=60,Y=30

answer will be 1

put value of x and y
