3 parts: List the ratios for using angle A as the angle of reference reduce when necessary

dezoksy [38]

Answer:

$\sin{A}=21/29\\\cos{A}=20/29\\\tan{A}=21/20$

Step-by-step explanation:

The sine of an angle in a right triangle is the ratio of the side across from the angle with the hypotenuse of the triangle (the hypotenuse is the side across from the right angle). In this case, the sine of angle A, shortened to $\sin{A}$ , is $21/29$ .

Cosine is short for "complementary sine." If the angles A + C = 90, the cosine of A is equal to the sine of C, since A and C are complementary. So $\cos{A}=\sin{C}=20/29$ . Notice that this ratio is the same as the ratio of the side adjacent to angle A (AB), to the hypotenuse.

The tangent is the ratio of the side opposite an angle to the side adjacent to it. Here, $\tan{A}=21/20$ . So, our trig ratios for this angle are

$\sin{A}=21/29\\\cos{A}=20/29\\\tan{A}=21/20$

What is the slope of the line that passes through the points (2, 3) and (8, 6)

nadezda [96]

Answer:

The slope of the line that passes through the points (2, 3) and (8, 6) is $\frac{1}{2}$ .

Step-by-step explanation:

To find the slope of two points, divide the difference between the y values by the difference between x values, you can remember this by the mnenomic "rise over run". In this case, the difference between y and x values would be 6 - 3 = 3 and 8 - 2 = 6 respectively. This means the slope between the two points (2, 3) and (8, 6) is $\frac{3}{6}$ or $\frac{1}{2}$ .
