Question

if o is the centre of the circle angle angle c a b is equals to 50 degree and angle c equals to 90 degree find angle ACB​

Answer 1

Answer:

here to find angle ACB we just have to find out angle C here a+ o is equal to c {ex.angle is equal to sum of int.opp} a is 50 and o is 90

=50+ 90

= 140

so x or angle c is 140° and ANGLE ACB is also 140° hope u got ur ans

Answer 2

Answer:

Angle ACB is given already = 90°

x = 50

Step-by-step explanation:

angle ADC = 90°

angle CAD = 50 °

THEREFORE angle ACD = 40 °

SINCE SUM OF ALL ANGLES IN TRIANGLE IS 180°

angle ACB = angle ACD + angle DCB

angle DCB = 50 °

x = 50 °
