Find the slope between the points (-3, -2) and (5, 4) (type in integer or reduced fraction you found only)

DiKsa [7]

Answer:

The slope is: $\frac{3}{4}$

Step-by-step explanation:

The equation for slope is:

$m=\frac{y_{2}- y_{1} }{x_{2} -x_{1} }$

Point 1: -3= $x_{1}$ , -2= $y_{1}$

Point 2: 5= $x_{2}$ , 4= $y_{2}$

4-(-2)=6

5- (-3)=8

6/8=3/4

The hypotenuse of a right triangle is 6 inches. if one of the legs is 2 inches, find the degree measure of each angle

miskamm [114]

A and b are the 2 smaller sides, and c = hypotenus; only for right triangles,
Pythagorean Theorem states that:
${c}^{2} = {a}^{2} + {b}^{2}$
given c = 6 in., a = 2 in.
${c}^{2} = {a}^{2} + {b}^{2} \\ {6}^{2} = {2}^{2} + {b}^{2} \\ {b}^{2} = {6}^{2} - {2}^{2} = 36 - 4 \\ \sqrt{ {b}^{2} } = \sqrt{36 - 4} = \sqrt{32}$
$b = \sqrt{32} = \sqrt{16} \times \sqrt{2} = 4 \sqrt{2} \\ b = 5.66 \: inches$
So the three side are 2, 6, and 5.66 inches
