Question

I need help with this one, anyone???

Answer 1

HELLO...!!

a = x

b = 21

c = 29

Phytagoras formula: a² + b² = c²

`x^2+(21)^2=(29)^2\\ \\x^2+441=841\\ \\x^2=841-441\\ \\x^2=400\\ \\x=√(400)\\ \\x=20\quad\Longrightarrow\boxed{\boxed{\mathbb{ANSWER\ \checkmark}}}\\ \\ \\\textbf{HOPE THIS HELPS...!!}`
