find the degree measure of-
m< x
m< y
m< z

x = 59, y = 59, z = 62

Step-by-step explanation:

This is an isosceles triangle, therefore, the angles that are across from the congruent sides are also congruent:  x = y

We also know that by the Triangle Angle Sum Theorem, that all the angles of the triangle add up to equal 180 degrees.

Therefore, x + y + z = 180 and, subbing in our expressions gives us

2x + 31 + 2x + 31 + 5x - 8 = 180 and

9x + 54 = 180 so

9x = 126 and

x = 14

That means that x and y have measures of

2(14) + 31 = 59

If those are 59 each, then

z = 180 - 59 - 59 so

z = 62

Let's check and make sure that sum is in fact 180:

59 + 59 + 62 = 180

2nd one in the first row is correct

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
