The slope of a line is defined as

m = \dfrac{\Delta y}{\Delta x}=\dfrac{y_2-y_1}{x_2-x_1}

In your case, we have

m = \dfrac{7-3}{8-1} = \dfrac{4}{7}

Answer:

The measure of the first angle is 32° and the measure of the second angle is 49°. (h = 32° & c = 49°)

Step-by-step explanation:

For the first triangle, we know that when you add up all the angles in a triangle, you'll end up with 180°. Keeping that in mind, all you have to do to find the third angle is add up the two we already know and subtract it from 180°.

1. 58° + 90° = 148°  -->  I know that the second angle is 90° because it's a right

180° - 148° = 32°           triangle.

2. 82° + 49° = 131°

180° - 131° = 49°

Hope this helps,

A spinner has five sections, labeled A, B, C, D, and E. The spinner is spun 45 times, and the results are recorded in the table.
Shkiper50 [21]
B. because it is spun 45 times. 45 + 45 = 90.

20 goes into ninety 4 1/2 times. it would probably be 18%

Does it matter which dimensions you select for the length and the width when you find the area of a rectangle? Explain. I need t
Sveta_85 [38]

Answer:

The area of a rectangle is the product of the length and the width of the rectangle.

The dimensions chosen for length and width of a rectangle must be the lengths of two adjacent sides. The area is the product of the two dimensions. It does not make a difference which one you call length and which one you call width since length * width = width * length because of the commutative property of multiplication.,
