Question

Hi guys,please solve this​

Answer 1

Answer:

angle ACB=36° angle CBD=47°

Step-by-step explanation:

Here,

angle A+angleABC+angleACB=180°( angle sum property)

angle A=90°(angle in a semicircle is a right angle)

so, angle ACB=36°

similarly in ∆BCD,

angleD+angleCBD+angleBCD=180°

angle D=90°

so,angleCBD=47°

Hope it helps!!

Answer 2

Answer:

measure angle 60 + measure angle 60 + measure angle 60 =180°

measure angle ABC= 54°

similarly

measure angle BDC = 90°

measure angle 60 + measure angle 60 + measure angle 60 = 180

measure angle DBC = 54°
