Question

iii)
iv)
State whether 11, 60, 61J 15 d Pymus
In the figure, O is the centre of the circle and AB is the diameter.
If <CAB = 38° then find the measure of ACB and CBA.
​

Answer 1

Answer:

<ACB =90°

<CBA=52°

Step-by-step explanation:

<ACB =90° (angle substended by a diameter at the circumference )

In ∆ABC , By angle sum property

< CBA + <BAC + <ACB =180°

<CBA+38°+90° =180°

<CBA=180°-128°

<CBA=52°

Answer 2

Step-by-step explanation:

if figure is a sentence of circle and ab is the diameter if cab =38° then find measure of acb and cba solution
