Pls help and show how do show it on paper

there is really no way to show but all you have to do is look at the angle across from angle 1 which is angle 4 because it is vertical to angle 1. hope that helps

it 4

Step-by-step explanation:

because both sides are symmetrical and you don't need paper to do it and it's a 90-degree angle so you tell by looking.

hope this helps

my best guesses would have to be either 4.5 or 2. p.s. if they're wrong, i'm so sorry for giving you the wrong answer.

well it says right there your brother is 13; "your age". so lets keep it simple. you are 13 years old and there is no way to put this into any kind of equation without wanting to tear your hair out. who came up with this?
