Question

Find x°. (Please send proper solution)​

Answer 1

Answer:

x⁰ = 50⁰

Step-by-step explanation:

∠ABC = 90⁰ (∵ angle in a semicircle)

From ∆ABC

∠ACB = 180⁰ - (∠CAB + ∠ABC)

= 180⁰ - (40⁰ + 90⁰ )

= 180⁰ - 130⁰

= 50⁰

∠ADC = ∠ACB. (∵ angles on the same segment)

x⁰ = 50⁰

Answer 2

Answer:

50

Step-by-step explanation:

In ∆ABC, <ABC=90° for being an angle on the diameter AC.So, <ACB=180°-40°-90°=50°.

And here<ACB=<ADB for being two angles on a same chord AB.So,<ADB=50°.

So,x=50.
