Question

plz give me correct plz plz​

Answer 1

Answer:

i) measure of angle CAB =90°

Reason: Tangent theorem

ii) Distance= 6cm

Reason: Radii of the circle

iii) d(BC) = 3√8 cm

Reason: By pythagoras theorem

d(CA)^2 + d(AB)^2 = d(BC)^2

6^2 + 6^2 = d(BC)^2

36 +36 = d(BC)^2

72 =d(BC)^2

√72 =d(BC)

3√8 =d(BC)

iv) measure of angle BAC = 45°

Reason: It is an isosceles triangle

Angle CAB = 90°

So the remaining angle should be 45°
