how to slove this question ​

Answer 1

Answer:

a) x= 30°, y= 30°

b) Triangle/ Scalene Triangle (all angles are different)

Step-by-step explanation:

a) Sum of angles of a triangle is 180°.

∠BAC + ∠ACB +∠CBA = 180°

x + y + 4y = 180° ---(1)

and, ∠ACB +∠ACD = 180°

y + 5y = 180°

6y = 180°

y = 30°

Substituting y=30 in eq 1,

x + 5y = 180°

x + 5(30°) = 180°

x + 150° = 180°

x = 30°

Answer 2

Answer:

x=30' y=30' is the answer. hope it helps you. Thanks.
