Question

Please help me on this thing

Answer 1

68 cm

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)= √((5,929) - (1,296))`

`c^(2)= √(4633)`

c ≈ 68 (rounded from 68.07)
