ANSWER THIS,
QUESTION IS IN THE ATTACHMENT.

✔️EXPLAIN IT✔️​

Answer 1

CBA = 90( AS diameter subtend 90 at any point)

ACB= 50

CAB= 180-90-50 = 40

AS CAT = 90( AT is tangent and CA normal)

So CAT = CAB + BAT

BAT = CAT - CAB= 90 -40 = 50

Answer 2

angle CBA=90 degree ( angle in the semicircle are of 90degree)

In triangle ABC,

angle A+angleB+angleC =180degree (ASP)

50+90+angleA=180

140+angleA=180

angleCAB=180-140

=40 degree

angle CAT=90 degree

also angleCAT =angle CAB+angleBAT

angle BAT=angle CAT -angleCAB

BAT=90-40

=50 degree
