Angle a is a vertical angle with the 30 degree angle above it. We know two of the 3 angles measures in the triangle, 30, 90 and b. All the angles in a triangle = 180 degrees.

30 +90 =120

180 -120 = 60

The measure of b is 60 degrees

angle c and 75 degrees are supplementary angles since a line is 180 degrees.

we can subtract 75 from 180 to find the measure of c.

180-75 =105

Angle a: 30 degrees

Angle b: 60 degrees

Angle c : 105 degrees

Simplify it and you get : -5/2

Slope is -5/2

Eula needs to buy binders that cost $4 each and notebooks that cost $2 each. She has $20. The graph of the inequality 4x + 2y ≤
Zolol [24]
She has to buy both binders and notebooks. So, you have to take into account that she has to have both. The closest you can get to $20 while still getting notebooks, is to buy 4 binders. 4 times 4 equals 16. So, she can get 4 binders and 2 notebooks, because then, 2 times 2 equals 4 and 16 plus 4 equals 20.
