Question

5.In the given figure PQ II RS BA perp RS and /_BCA=50^(@) find /_BAC and /_CAS.​

Answer 1

Answer:

the sum of atriangle is 180degree

rs is perpendicular to ba

so angle and is 90degree because of perpendicular of ab and rs

and angle bca is given 50degrwe

by property of triangle angle

angle bas+angle bac+angle acb=180degree

angle bas+90+50=180

angle bas=180-90-50

angle bas=180-140

angle bas=40degree
