Question

heigh=20,base=x, hypotenuse=17​

Answer 1

Answer:

Height² + base² = hypotenuse²

20²+ base² = 17²

400 + base² = 289

Base² = 289 - 400

Base = √111

Hope u got it...

Answer 2

Answer:

IN A TRIANGLE , ABC

B IS AT 90 DEGREE

AB= 20

AC= 17

By Pythagoras theorem

$h ^{2} = b ^{2} + p ^{2} \\ ac ^{2} + bc {}^{2} + ab {}^{2} \\ \\ 17 {}^{2} = x { + 20}^{2} \\ 289 = x + 400 \\ x = 400 - 289 \\ </strong><strong>✓</strong><strong>111ans$
