The angles are in the ratio of 5:6:9.
Let the angles be represented by:

5x, 6x, and 9x.

The sum of the interior angles of a triangle is 180.
5x + 6x + 9x = 180
20x = 180
x = 9

The angles are 5*9 = 45,
6*9 = 54,
and
9*9 = 81.

Point A lies on the circle and has an x-coordinate of 1.

stellarik [79]

Answer:

$\sqrt{(0-y)^{2}+(0-1)^{2}}=2$

Step-by-step explanation:

we know that

In the circle of the figure the radius is equal to 2 units

The distance from the center of the circle (origin) to the point A must be same at the radius

Applying the formula's distance between two points

point A( 1,y) and point (0,0)

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute the values

$2=\sqrt{(0-y)^{2}+(0-1)^{2}}$

rewrite

$\sqrt{(0-y)^{2}+(0-1)^{2}}=2$

Scores on a test have a mean of 70 and q3 is 83. the scores have a distribution that is approximately normal. find p90. (you wil

Hunter-Best [27]

<span>Answer: Q3 represents 75%, meaning a z of ~0.67 80 - 70 is 10, so the standard deviations is ~14.9. 10 / 0.67 = 14.9 now find the z that represents a score of 90 90 - 70 is 20 20 / 14.9 = 1.34 from a z-table, a z of 1.34 represents a probability of ~90.99% meaning that there is about a 9.01% chance of getting a 90 or better.</span>
