Question

ABC is a right angled triangle. if B = 90°, AC = 96 cm, C = 30°. What
dose AB = ?

Answer 1

heya

here is ur answer

➡using trigonometry ratios v can find it

➡sin 30° = AB / AC

➡1/2 =AB / 96

➡96= 2AB

➡AB = 96/2

➡AB = 48 cm

⭐⭐⭐ AB = 48cm ⭐⭐⭐

Answer 2

Given - B = 90°, AC = 96 cm, C = 30°

Find - Length of AB.

Solution - The length of AB is 48 centimetres.

As per the given information, the side AB will be prependicular and AC is hypotenuse.

So, taking sine of angle 30° to find the length of AB. As, sin theta = perpendicular/hypotenuse.

sin 30° = AB/96

Value of sin 30° = 1/2

So, 1/2 = AB/96

AB = 96/2

Performing division to find value of AB.

AB = 48 centimetres

Thus, length of AB is 48 centimetres.
