Question

Find the measurement of the missing side. Round all answers to the nearest tenth.

Answer 1

Explanation:

Right angled triangle. To find the missing side use Pythagorean theorem.

Base² + altitude² = hypotenuse²

7² + x² = 23.2²

49 + x² = 538.24

x² = 538.24 - 49

x² = 489.24

Take square root,

x =
`√(489.24)`

x = 22.1 mm
