Answer 2

Answer:

68 cm

Step-by-step explanation:

Use the following formula (Pythagorean Theorem) to solve for c:

$c^{2}= \sqrt{(a^{2}) - (b^{2})$

Substitute values:

$c^{2}= \sqrt{(77^{2}) - (36^{2})$

Simplify:

$c^{2}= \sqrt{(5,929) - (1,296)}$

$c^{2}= \sqrt{4633}$

c ≈ 68 (rounded from 68.07)
