Question

If angle DAB is 60 degree and angle AbD is 50 degree then find angle ACB

Answer 1

Answer:

Angle ACB = 70

Explanation:

When we add 60+50 =110 so we subtract 180 -110 =70

Answer 2

The angle of  ACB  

Explanation:

• In △ABD, ∠ABD = 50° and ∠DAB = 60°, ∠ADB = ?

• ∠ABD + ∠ADB + ∠DAB = 180°   [angle sum property of triangle]  

• 50° + ∠ADB  + 60° = 180°

• ∠ADB = 180°  - 110

• ⇒ ∠ADB  = 70°

• Now, ∠ACB = ∠ABD =  70° [∵ angle in same segment]
