Please help me <br> can u explain how to do this
Ghella [55]

Answer:

x=41

Step-by-step explanation:

so since this is a right triangle you can use the Pythagorean Theorem to find the missing side. the two sides you know are 'a' and 'b' and the missing side is 'c'. the theorem says that:

a^2+b^2=c^2

so:

9^2 +40^2=c^2

solve for the exponents:

81 +1600=c^2

1681=c^2

and now, since 1681 is the missing side's length squared, we must find the square root of 1681, which is 41

hope this helps :)

DochEvi [55]

Answer:

24

Step-by-step explanation:

Given the solution

2 < x ≤ 24

The ≤ symbol means less than or equal to

Thus x can equal 24

At the other end 2 < x which means x cannot equal 2

Thus x = 24 will make the inequality true
