Question

Can you find out what X equals.

Answer 1

Explanation:

Pythagoras theorem may be used :

as we can see pq iS perpendicular on oq

OQ²+pq² = op²

x² + (9)² = (3)²

x²+81= 9

x² = 81-9

x²= 72

x = √72

x = 8.48528137 ✓

Answer 2

Explanation:

OQ²+pq² = op²

x² + (9)² = (3+x)²

x²+81= 9+ 6x +
`x^(2)`

6x=72

x=12
