Question

In the given triangle calculate theta if angle b = 90° ab = 20 cm and ac = 40°​

Answer 1

Answer:

30

Step-by-step explanation:

sin C = AB/AC =20/40 =1/2 = sin 30

 ANGLE   is  30

Answer 2

The value of θ is 30°.

Step-by-step explanation:

Given information: In triangle ABC, b = 90° AB = 20 cm and AC = 40 cm.

We need to find the value of θ.

Hypotenuse = AC = 40 cm

Opposite side = AB = 20 cm

In a triangle angle triangle,

$\sin \theta = \dfrac{Opposite}{Hypotenuse}$

$\sin \theta = \dfrac{20}{40}$

$\sin \theta = \dfrac{1}{2}$

$\sin \theta = \sin (30^{\circ})$

On comparing both sides we get

$\theta =30^{\circ}$

Therefore, the value of θ is 30°.
