Answer:

7/4 or 1.75

Step-by-step explanation:

Assuming this is a linear function, you can use the slope formula of change in y-values divided by change in x-values. Take your y-values (8 - 1), which is seven. Then take your x-values (6-2), which is equal to 4. Then your slope is just 7/4 or 1.75.

Answer:7/4

Step-by-step explanation:

(6,8) (2,1)

x0=6

y0=8

x=2

y=1

slope=(y-y0)/(x-x0)

Slope=(1-8)/(2-6)

Slope=-7/-4

Slope=7/4

How long is line UW?
Neko [114]

Answer: UW= 9√3

Step-by-step explanation:

This right triangle is a 30-60-90 triangle. This is a special triangle. Since this is a special triangle, the hypotenuse is 2x.

The hypotenuse is 18. We can figure out the length of x.

2x=18

x=9

Since we got 9, you would think it is the answer, but it's not. The length across the 60° angle is x√3. Now that we know the length across from 60°, we can plug in x.

9√3

We can check our answer by using Pythagorean Theorem.

9²+(9√3)²=18²

81+243=18²

324=324

Since they are equal, we know we have the right answer.

Find the missing side or angle round to the nearest tenth b=15 a=30 c=29 A=[?]°
pogonyaev

Answer:

71.6056

Step-by-step explanation:

c² = a² + b² - 2abcosC°

29² = 30² + 15² - 2(30)(15)cosC°

841 = 900 + 225 - 900cosC°

-59 = 225 - 900cosC°

-284 = -900cosC°

71/225 = cosC°

cos⁻¹(71/225) = C°

C° = 71.6056
