In the diagram CD is tangent to circle B at point C. If AB = 5 cm, and BD = 13 cm, find AD. Round the answer to the nearest tenth.

Step-by-step explanation:

The value of AD is found by using the Pyhagorean Theorem:

Besides, BD is measured in terms of the Pythagorean Theorem:

By Algebra:

15.6 cm

Step-by-step explanation:

Given that AB = 5 cm, then BC = 5 cm, and AC = AB+BC = 10 cm

Applying Pythagorean theorem to triangle BCD:

BD² = BC² + CD²

CD = √(BD² - BC²)

CD = √(13² - 5²) = 12 cm

Applying Pythagorean theorem to triangle ACD:

AD² = AC² + CD²

AD = √(AC² + CD²)

AD = √(10² + 12²) = 15.6 cm
