Answer:

8.) x=115 degrees

9.) y=102 degrees

Step-by-step explanation:

8.) A triangles total degrees is 180, so 180-50=130. now the missing angles are congruent, so 130/2=65. and now we're working on the bottom right angle. which is 65. what we need can be added to the angle we just found to add up to 180, so reverse it. 180-65=115. so x=115 degrees.

9.) because y is congruent to the angle across from it, we can just assume y and 78 is equal to 180. 180-78=102. so y=102 degrees. Hope this helps!

First, solve 7 times square root of 5.

7 x 2.236 = 15.652

Now find the solution above that results in 15.65.

We can quickly eliminate the top 2 as they will result in very large numbers.

The bottom problem is quick to check - simplifies to (7 + 5)/5 = 2.4. No

It looks like the next to last answer is our best bet.

Figure the square root of 196 (14) and multiply by square root of 5 (2.236). Giving us 31.304.

Divide the result by 2. And that gives us 15.652.

If you knew the square root of 196 was 14, it was helpful to find this quickly because 14/2 = 7 and then the other square root was the 5 from the problem.

What is the slope of the line that passes through the points (5, 4) and (13.25, -18) ?

Murrr4er [49]

Answer:

Answer: D. 8/3

Step-by-step explanation:

Formular for slope:

[ consider points (x1, y1) and (x2, y2) ]

$slope = \frac{y_{2} - y _{1} }{x _{2} - x _{1} } \\$

x1 » 5, y1 » 4

x2 » 13.25, y2 » -18

$sloe = \frac{ - 18 - 4}{13.25 - 5} \\ \\ = \frac{22}{8.25} \\ \\ { \boxed{ \boxed{slope \: = \frac{8}{3} }}}$
