Can you please help me and explain this in a way that I can understand

180 Degrees

Step-by-step explanation:

So, m∠1 = m∠2 = m∠3 means that these angles are the same degrees

The question asks whats the degree of m∠CDG so first we find those points. In this image, it looks like points C,D and G form a line which is also equivalant to 180.

I hope you understand! If not, i'll try to elaborate more

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
