Question

(HIGH POINTS AWARDED) Hi, i have a question regarding Geometry in Maths, i would really appreciate the help!

Answer 1

Answer:

y=30°

as that is a right angled triangle and right angled triangle all angles are 90+30+60=180

Answer 2

Answer:

45⁰

Step-by-step explanation:

angle ACB = 90⁰ ( Angle made by diameter)

triangle AOC congruent to triangle BOC ( SAS rule of congruency)

so

angle ACO = angle BCO ( CPCT)

y = Angle BCO

angle ACO +angle BCO = angle ACB

y + y = 90⁰

2y = 90

y = 45

this was your answer and explanations
