Question

Two perpendicular sides of a right angled triangle are 15cm and 8cm long.find the length of the hypotenuse side

Answer 1

Answer:

17 cm

Step-by-step explanation:

here,let perpendicular be 15cm and base be 8cm.

(remember that,here we can say the base as another perpendicular side because it's perpendicular to the perpendicular side.. don't get confused.)

according to the Pythagoras theorem:

(p)^2+(b)^2=(h)^2

15^2+8^2=225+64=289

√289=17

(here I found the square root of 289 because we are asked for only h ...not for the h^2)

hence,the hypotenuse is of 17 cm.
