Question

if tan A = that find
a sin A
os B - COSA sin B
sin sinB t cOS A COSR
Note: right angle is
at c.​

Answer 1

Answer:

answer is a) 1/2 and B) √3/2

Step-by-step explanation:

tan A=√3...... angle A= 60degrees

we know that angle the and c is at right angle so ,angle C=90degrees

so angle b=30 degrees

a) sinAcosB- cosAsinB.....for this formula sin (A-B)

=sin (A-B) =sin (60-30)

=sin(30) =1/2

b) sinAsinB+cosAcosB...... for this formula cos(A-B)

=

cos (A-B) = cos(60-30)

=cos(30) =√3/2
