What is the difference between adjacent and vertical

Hi there

Adjacent angles are two angles that have a common side and a common vertex (corner point), and don't overlap. Vertical angles are the angles opposite each other when two lines cross

Vertical means upright and is perpendicular to the horizontal plane, which in day to day terms means the ground if we can assume for a moment that the ground is flat at least locally around us. It can mean overhead - of or at the vertex.

Adjacent on the other hand means the one next to it, its neighbour, also may mean bordering or close or nearby. It is near but not necessarily in contact although often you may find they are touching but that is perhaps more precisely then described as adjoining.

Step-by-step explanation:

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
