Question

in a right angle triangle ABC ang B equal to 90 degree, AC equal to 17 cm and AB equal to 8 cm find the length of Bc.​

Answer 1

Answer:

BC = 15 cm

Step-by-step explanation:

Given that

ABC Is a right angled triangle with B= 90°,

Hypotenuse AC = 17 cm

and Perpendicular = 8 cm

To find, Base BC

Using Pythagoras theorem

Hypotenuse² = Base² + Perpendicular ²

17² = BC² + 8²

289 = BC² + 64

289 - 64 = BC²

225 = BC²

√225 = BC

15 cm = BC
