Answer 1

Answer:

289 is the correct answer

Answer 2

Answer:

▪As per the pythagoras theorem,

let the side with 15cm be base and the side with 8cm be the altitude.

Then x is the hypotenuse

▪As per pythagoras theorem:

$hypotenuse = \sqrt{ {base}^{2} + {altitude}^{2} }$

Base=15cm

Altitude =8cm

x(hypotenuse)=

$\sqrt{ {15}^{2} + {8}^{2} } = \sqrt{225 + 64} = \sqrt{289} = 17$

☆c=17cm
