I need help with 10 11 and 12 PLEASE

Angle 6 is 42 degrees

Angle Q is 56 degrees

Angle is 74 degrees

Let me know if this helps :)

351.23

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
