Answer:

80 degrees

Step-by-step explanation:

A triangle has 180 degrees so you have to add up the two angles with measurements you know (70 + 30= 100) and subtract 100 from 180

A: It would be 80 degrees. :)
E: This is because all triangles equal 180 degrees so if you already have 2/3 angles then it’s pretty easy to determine the last angle. Angle B + Angle A = 100 (70+30=100). So just subtract 180 by 100 and you get 80 degrees!

We are given that the cost of each shirt = $12.25

It is given that she bought total 'x' shirts, each of cost $12,25.

So, the cost of 'x' shirts is dollars

Also, there is a shipping charge of $3.99

So, the total cost of 'x' shirts is
