What is the value of x?

20
35
60
70

The given angles are =

(x+40)° and 3x°

As the given angles are opposite to each other on the intersecting lines, so they are vertical angles. These are congruent or equal.

So,

Hence x = 20°

The given angles are =

(x+40) = 20+40 =60°

3x = 3*20 =60°

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
