Question

Kindly explain this STEP BY STEP

Answer 1

Step-by-step explanation:

H=17cm

let a and b be other sides

consider a=8cm

Now apply Pythagoras theorem

$(hypo) {}^{2} = (perpendiculr) {}^{2} + (base) {}^{2}$

(

${17}^{2} = (8) {}^{2} + b {}^{2}$

289=64+b^2

289-64=b^2

b^2=225

b=15

Hence the Length of the third side is 15 cm

Answer 2

Answer:

Length of the other side is 15

Step-by-step explanation:

In a right angle triangle,

Given that hypotenuse is 17 cm

One of the side is 8 am

By using Pythagoras theorem,

       Side 1 ² + Side 2² =  hypotenuse²

            8 ²   +  Side 2² = 17²

        Side 2² = 289 - 64

        Side 2² = 225

        Side 2 = √225

        Side 2 = 15
