Question

In the picture, P is the centre of the circle . If angle ABC =40°, angle BAC=80° then
(a) what is angle ACB ?
(b) what is angle CAP ?
(c) what is angle APC ?
(d) If BQ =25cm, what is the
perimeter of ∆ABC?​

Answer 1

Answer:

a) angle ACB= 60° ( using angle sum property)

b) angle CAP= 10° (Angle BAP is 90° because it is

a tangent )

c)angle APC= 140°

d) perimeter= 25+25 = 50cm
