Question

Hurry ASAP

Answer 1

Answer:

B. It is incorrect because the length of the unknown side is the square root of 7,744.

Step-by-step explanation:

The hypothenuse is 137 units.

One legt is 105.

Using Pythagorean's Theorem, we have

$a^{2} =b^{2} +c^{2}\\ (137)^{2}=(105)^{2}+c^{2}\\c=\sqrt{(137)^{2}-(105)^{2}} \\c=\sqrt{18,769-11,025} =\sqrt{7,744}\\ c = 88$

Therefore, Gina's process is uncompleted, because the length of the missing leg is the square root of 7,744, which is 88.

So, the right answer is B.

Answer 2

Answer:

The answer is C It is correct because the length of the unknown side is the difference of the lengths of the sides.

Step-by-step explanation:

137^2-105^2=88^2

18,769-11,025=7,744

88*88=7,744
