Answer:
Step-by-step explanation:
You used Pythagorean theroem which is correct as this does form a right triangle however 50 is the hypotenuse as the ladder is propped up against the wall. 30 would then be the height of the triangle and the base is unknown so...
50 squared minus thirty squared gives 1600 so:
Therefore x is the square root of 1600 which is 40
This type of question is very rare on Brainly. It's always a special
occasion when one comes along. I call this a "twofer".
Wherever this question was copied from, it clearly had both a
quadratic equation and a list of (4) methods along with it. Sadly,
the individual who expects to be handed a fully-developed set of
answers on a silver platter chose to share neither of them with the
volunteers whose assistance he so earnestly solicits.
One might just as well come along and post:
<em>"Answer the following question, using the following words." </em>
and then leave it at that, for others to puzzle over.
1 - 2/3 = 1/3
1+ (-1/3) = 2/3
