Answer 2

Answer:

$∠CAD= 10°$

Step-by-step explanation:

In the given figure ∠ABD= 90° and ∠ADB = 30°

We have to find ∠CAD

Now in Δ ADC

As we know the exterior angle property which states that : The exterior angle is equal to the sum of opposite interior angles .

Therefore

∠ADB= ∠CAD+ ∠ DCA

⇒30°= ∠CAD + 20°

⇒∠CAD = 30° - 20°=10°

b) is the correct option

Hence, the value of ∠CAD = 10°
