a. 9 units, 12 unitsb) 11 units, 10.2 unitsc)4.9 units, 15.8 unitsd)4.9 units, 14.2 unitse)5.2 units, 14.1 units

Answer 1

For plato users the correct option is D.

Explanation:

D. 4.9 units, 14.2 units

Answer 2

Remake

The Pythagorean Theorem's formula is a^2 + b^2 = c^2 .

Step 1: Apply the numbers:-

4.9^2 + 14.2^2 = c^2

24.01 + 201.64 = c^2

225.64 = c^2

Step 2 : Apply the radicals and solve:-

√225.64 = √c^2
