Question

Find the length of a side of the triangle when the hypotenuse and the other adjacent side are given. Hypotenuse=12.3cm ,One adjacent side=12cm, Second adjacent side=?​

Answer 1

Answer:

2.7 cm

Step-by-step explanation:

Hypotenuse, h = 12.3cm

One adjacent side, p = 12cm

Second adjacent side, b = ?

Using Pythagoras theorem: p² + b² = h²

⇒ 12² + b² = 12.3²

⇒ 144 + b² = 151.29

⇒ b² = 151.29 - 144 = 7.29

⇒ b = √7.29

⇒ b = 2.7 cm

Other adjacent side is 2.7 cm.

Answer 2

Answer:

the second adjacent side is 2.7 cm.

Step-by-step explanation:

we know that,

h²=b²+p²

⇒ (12.3)² = 12² + p²

⇒ 151.29 - 144 = p²

⇒ 7.29 = p²

⇒ p = √7.29

⇒ p = 2.7
