I dunno I rlly don't know like seriously I'm in 7th
Step-by-step explanation:
There can be a lot of math expressions that may equal 13. Here are some of the expressions that equal 13.
Now, let us consider some interesting expression

If the value of x = 2, then the expression will be equal to 13.
i.e.
∵ when x = 2
Considering a word problem
<em>'Tom has 10 oranges while Tony has 3 more oranges than Tom. How many oranges Tony has?</em>
Let 'x' be the number of oranges Tom has.
The number of oranges Tony has = x + 3
as Tom has 10 oranges, so x = 10
Therefore, the number of oranges Tony has = x + 3
= 10 + 3 = 13
Therefore, the number of oranges Tony has = 13
4x = 157.2
4x/4 = 157.2/4
x = 39.3
An outside angle is equal to the sum of the two opposite inside angles.
The two opposite inside angles from X are 63 and 46.
X = 63 + 46 = 109 degrees.
