Find the value of a and b​

a=50

b=120

Step-by-step explanation:

a)180-70-60=50

b)180-60=120

Step-by-step explanation:

b = 180 -60 = 120 degree

the triangle angles sum = 180

180= 60 + 70 + a

a = 50

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
