Solve for x PLS PLS PLS HELP!!

Answer 1

A. 12

You use the formula A2+B2=C2
6^2+10^2 = X^2
36+100=x^2
136=x^2
Square root both sides
X= 11.6 round up to 12

Answer 2

Answer:

Option C. 8

Step-by-step explanation:

It is a right triangle.

let

AC = 10

BC = 6

AB = x

Using Pythagoras theorem

${ab}^{2} + {bc}^{2} = {ac}^{2} \\ {x}^{2} + {6}^{2} = {10}^{2} \\ {x}^{2} = {10}^{2} - {6}^{2} \\ {x }^{2} = 100 - 36 \\ {x}^{2} = 64 \\ x = \sqrt{64} \\ x = 8$
