Question

find the length of BC and AC...

please I need this answer...​

Answer 1

Answer:

• In triangle ABC shown, suppose that the length of the hypotenuse is 14cm and that a = BC = 3cm. Find the length of AC. c2 = a2 + b2 142 = 32 + b2 196 = 9+ b2 b2 = 196 − 9 = 187 b = √187 = 13.67 (2dp.) The length of AC is 13.67cm.

Answer 2

Step-by-step explanation:

Example In triangle ABC shown, suppose that the length of the hypotenuse is 14cm and that a = BC = 3cm. Find the length of AC. c2 = a2 + b2 142 = 32 + b2 196 = 9+ b2 b2 = 196 − 9 = 187 b = √187 = 13.67 (2dp.) The length of AC is 13.67cm.
