An angle is 12 more than 2 times its supplement. Determine the measure of each angle.

Answer 1

@dude

Answer 2

@Shadow

Answer 3

Y is 5 more than 4 times of x

Y = 4x +5

Answer 4

Supplementary means it adds up to 180

Answer 5

Do you see how to do this one?

Answer 6

yea

Answer 7

so its 12+2x=180

Answer 8

no

Answer 9

Using my example from earlier. Lets say angle y and angle x are supplementary (they add up to 180).

y is 5 more than 4 times of x.

Therefore y = 4x + 5

y + x = 180
x + 4x + 5 = 180

Answer 10

or if it looks better this way..

y + x = 180
4x + 5 + x = 180

Answer 11

so y=2x+12
x+y=180

Answer 12

Correct

Answer 13

then how did ur equation equal 4x+5+X=180

Answer 14

You can't solve for a variable if there is another variable. So you define that variable.

For my example, y = 4x + 5

So in x + y = 180, I can submit 4x + 5 for y

Answer 15

It's called substitution in math.

Answer 16

ah

Answer 17

so its actually 2x+x+12=180

Answer 18

yus

Answer 19

okie

Answer 20

are you sure? cus i got 3x=178

Answer 21

You subtracted 2. It is a 12.

Answer 22

ohhh oof. my mistake. 168

Answer 23

ok got it. x=56 and y=124

Answer 24

coolio
