Step-by-step explanation:

(x+20)=9x

4x=20

x= 5°

because GEF AND DEG ARE EQUAL

THEN DEF= 2 * GEF

DEF = (9*5)*2=90

DEF= 90°

Which conjunction about whole numbers is true?

alexandr402 [8]

Answer:

The sum of two even numbers is even and greater than the addends.

Step-by-step explanation:

Let 2n and 2m be two even numbers.

The sum of these numbers is

$2n+2m$

Use distributive property:

$2(n+m)$

This number is even because 2 is its factor.

Note that

$2n+2m>2n\\ \\2n+2m>2m$

Thus, correct option is:

The sum of two even numbers is even and greater than the addends.

yuradex [85]

Answer:

C. 6n - 5

Step-by-step explanation:

Hello!

A product of a number and 6 means we have to multiply a number by 6.

This can be shown by 6n.

Then 5 less means we subtract by 5.

We get the answer: 6n - 5

Find the point on the terminal side of θ = 3pi/4 that has a y coordinate of 1.

galben [10]

we are given with an angle of 3 pi over 4. As we convert this to degrees, we can see that it is equivalent to 135 degrees and is a second quadrant angle. when y-coordinate is equal to 1, we can find the point on the terminal side or the x-xis by using tan theta. tan theta is equal to y/x. x then is equal to -1.
