Find the angle measurements of the polygon

sum of angle measurements is 540°

x = 80

(x -15) =  145

(x - 25) =  135

Step-by-step explanation:

Add all the angles and equal them to 540

x + x + (x -15) + 100 + (x - 25) = 540

add x's and numbers together

x + x - 15 + 100 + x - 25 = 540

3x + 60 = 540

3x = 480

x = 160,

substitute into angles

x = (160) = 80

x = (160) = 80

(x -15) = 160 - 15 = 145

100

(x - 25) = (160 - 25) = 135

adding all angles equal to 540

step-by-step explanation:

this is not a question

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
