Answer 1

Question:-

Write an equation to determine the unknown side. Then solve the equation

Given:-

1. Right angle triangle
2. Hypotenuse = 12
3. Base = 4

Answer:-

To Find:- Perpendicular = x

Formula:- Pythagoras theorem

hypotenuse ² = perpendicular ² + base ²

h² = p² + b²

12²= x² + 4²

144 = x² + 16

144-16 = x²

128 = x²

✓128 = x = 11.3

So ATQ :- Round to the nearest tenth.

Your answer :- perpendicular = x = 11

so sides of triangle are

1. hypotenuse = h = 12
2. perpendicular = x = 11
3. base = b = 4

Answer 2

Answer:

11.314

Step-by-step explanation:

$12^{2}$ - $4^{2}$ = 128

$\sqrt{128}$ = 11.314
