1 answer:

5 0

Right triangle 30 60 90
short leg = 1/2 hypo = 4√2 / 2 = 2√2
so x = 2√2

long leg = short leg times √3 = 2√2 * √3 = 2√6
so y = 2√6

answer C.
x = 2√2 ; y = 2√6

The average of 10 numbers is −10. If the sum of 6 of them is 100, what is the average of the other 4? 20pts

Allushta [10]

Answer:

The sum of the other 4 numbers is $-200$

Step-by-step explanation:

Let

x------> the sum of 6 numbers

y-----> the sum of the other 4 numbers

we know that

$\frac{x+y}{10}=-10$ -----> equation A

$x=100$

substitute the value of x in the equation A

$\frac{100+y}{10}=-10$

$\frac{100}{10}+\frac{y}{10}=-10$

$10+\frac{y}{10}=-10$

$\frac{y}{10}=-10-10$

$\frac{y}{10}=-20$

$y=-20*10=-200$

If the measure of 0 is A radians and B degrees, then A=180B/pie

yKpoI14uk [10]

Yup that is correct, that is the way to convert measurements of angle from radians to degrees. because 2pi is equivalent to one revolution of a circle and in degrees is equal to 360 degrees, then simplifying it 360 / 2pi = 180 / pi.
so <span>the measure of 0 is A radians and B degrees, then A = 180 B/pi</span>
