Question

5 In the given figure, AB divides angleDAC such that the measure of the angleCAB is three times the measure of the angleDAB and AB = DB. Find the value of x.​

Answer 1

Answer:

54

Step-by-step explanation:

Hope it helps not so much sure about the ans

Answer 2

90⁰

Step-by-step explanation:

<CAB = 3 <DAB

Let <DAB = y

<EAC + < CAB + <BAD = 180⁰

[LINEAR PAIRS]

108 ⁰ + 3y +y = 180⁰

4y = 180⁰ -108⁰

y = 72/4 = 18⁰

Now, AB = DB

Then, <BAD = <BDA = y = 18⁰

<ADB + x = 108⁰

[ Exterior angle property]

18⁰ + x = 180⁰

x = 180⁰- 18⁰

x= 90⁰
