Question

In ABC; B = 90; find the values 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:

Sum of interior angles of triangle is 180

Answer 2

Answer:

ans is 1 i hope so you can find this helpfull

Step-by-step explanation:

Given in △ ABC, ∠B=90  

o . This given A+C=180 o −90 o =90 o ......(1)

. Now,

sinA . cosC+cos A. sinC =sin(A+C)

=sin(90 o )

=1.
