How to know when to use c2=a2+b2 or a2+b2=c2 in a question that doesnt have a shape

Viefleur [7K]

Step-by-step explanation:

A flagpole is 53 feet tall. Most of the time, this will be a vertical side of the triangle.

The flagpole and the ground are perpendicular to each other so they should form the legs of the triangles, this the triangle will be a right angle.

The rope will be the hypotenuse, the side opposite of the right angle.

Please help me, i don't get this

Answer:

A

Step-by-step explanation:

The rule is, whenever you plug in g(x) into f(x) or vice versa, they always must equal x. So if you plugged in g(x) into f(x), then the outcome should be x. If the output is not x, then they are not inverses.

What is m∠2 + m∠3? m∠2 + m∠3 =?

Serga [27]

Let's start with m∠1. m∠1 has to be 90º because line segment AB is perpendicular with line segment AC, as it shows a right angle symbol on the angle beside m∠1. Now that we know that, it will be much easier to find m∠2 and m∠3 because m∠1, m∠2 and m∠3 are part of the triangle formed in the middle, and all angles in a triangle add up to 180º. 180-90 is 90, therefore, m∠2 +m∠3=90º so all three angles add up to 180º. You don't even have to find the specific angle measurements.

Hope this helps. I also attached a (rather poorly edited) image.
