Can someone with these 2 ? i'm doing corrections.

2.  A = 30°

3.  x = 12

Step-by-step explanation:

2.

The angle OPPOSITE of the angle "8x +4" is also same because they are vertical angles (makes a "cross").

The angle beside (adjacent) to the 130 degree angle is 50. Because a straight line is 180 degrees. So 130 ADDED to WHAT will make 180?

130 + WHAT = 180

WHAT = 180 - 13- = 50

Now, we have all the 3 angles of a triangle. We know sum of 3 angles in a triangle is 180, thus we can write:

3x - 6 + 50 + 8x + 4 = 180

Now, we can first, solve for x:

The value of "x" is 12. But we need measure of Angle A which is "3x - 6". So we plug in x = 12 in it.

A = 3x - 6

A = 3(12) - 6

A = 36 - 6

A = 30°

3.

The Square inside the triangle means the angle is a 90 degree angle. The other 2 angles are shown as algebraic expression.

We know sum of 3 angles in a triangle is 180 degrees. Thus we can write an equation in "x" and solve for x. Shown below:

Thus, the value of x is 12

were is the chart?

step-by-step explanation:

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
