Find the x in the tringle

Answers

Answer 1

Answer:

Answer:

x = 9

Step-by-step explanation:

→You can use the Pythagorean Theorem to solve:

$a^2+b^2=c^2$

→The "a," and "b," are the legs, and the "c," is the hypotenuse. In this case, we are already given the hypotenuse as 41, and we are trying to find a leg:

$40^2+b^2=41^2$

$1600+b^2 = 1681$

→Subtract 1600 from both sides:

$b^2=81$

→To get "b," by itself, square root both sides, like so:

$√(b^2) =√(81)$

→81 is a perfect square meaning it has two factors that are identical.

$b = 9$

What is a=2x+6xz solve for x

Answers

To solve for x, we must first isolate that term!
a = 2x + 6xz ------> Factor out x
a = x(2+6z) ------> Now divide by (2+6z) to leave x by itself! This will give you an answer of
$x = (a)/(2 + 6z)$
