The hypotenuse of a right angled triangle of sides 12 cm and 16 cm is __________

#### Options

28 cm

20 cm

24 cm

21 cm

###### Advertisements

#### Solution

**20 cm**

**Explanation;**

Hint:

Side take a = 12 cm

b = 16 cm

The hypotenuse c^{2} = a^{2} + b^{2}

= 12^{2} + 16^{2}

= 144 + 256

c^{2} = 400

⇒ c = 20 cm

Activity: From given figure, In ∆ABC, ∠ABC = 90°, ∠ACB = 30°

∴ ∠BAC = `square`

∴ ∆ABC is 30° – 60° – 90° triangle

∴ In ∆ABC by property of 30° – 60° – 90° triangle.

∴ AB = `1/2` AC and `square` = `sqrt(3)/2` AC

∴ `square` = `1/2 xx 12` and BC = `sqrt(3)/2 xx 12`

∴ `square` = 6 and BC = `6sqrt(3)`
