The ratio of the measures of the angles of a triangle is 6:2:7. Find the measure of the largest angle.

VLD [36.1K]

Answer:

Step-by-step explanation:

6x + 2x + 7x = 180 Every triangle has a measure of 180o

15x = 180 Divide by 15

x = 180/15

x = 12

The longest side will be 7x

7*12 = 84

If the probability of an outcome is 2/9, what are the odds against that outcome?

IrinaVladis [17]

Answer:

7/9

Step-by-step explanation:

If the chances of an outcome are 2/9, the odds against it can be found by subtracting that from 1.

1 - 2/9

= 7/9

So, the odds against that outcome are 7/9

The points (2,-5) and (5,r) lie on a line with slope 2. Find the missing coordinate r.

Andrew [12]

Answer: r = 1

Step-by-step explanation:

The slope of a line can be represented as $\frac{y_2-y_1}{x_2-x_1}$ . Plugging in the following values would provide you with:

$\frac{(r)-(-5)}{(5)-(2)} =2$

$\frac{r + 5}{3} = 2$

$r + 5 = 6$

$r = 1$

Hope it helps :) and let me know if you want me to elaborate on anything.
