Answer:

28

Step-by-step explanation:

The interior triangle has a right angle, and one of its corners is 62, so the other angle, which is vertical to x, is 180-(90+62)=28, so x=28.

28 because the angle kd is 90 degrees so subtract 90-62 and you get 28 on the other side which x is the same as the other side hope it makes sense the answer is 28

Solve the system of linear equations by elimination. 3x+3=3y and 2x−6y=2
Drupady [299]
3x + 3 = 3y         < -- make this 3x - 3y = -3
2x - 6y = 2

multiply by 2 on the first equation
6x - 6y = -6
2x - 6y = 2           
subtract them

4x = -8
x = -2


substitute x = -2 into any of the equation
2x - 6y = 2
2(-2) - 6y = 2
-4 - 6y = 2
-6y = 6
y = -1

So the answer is 
(-2 , -1)

12. I don’t know how to do it
Nostrana [21]

Answer:

BC = 50

Step-by-step explanation:

I believe what I'm doing is correct but to be completely honest with you, I haven't done this in a while lol

Okay so...

You would do

1. 6y-16 = 4y+6

You would subtract 4 from 6...

2. 2y-16 = 6

You would then add 16 to 6...

3. 2y = 22

Then, divide 2 from 22...

4. y = 11

Substitute into BC...

5. 6 (11) - 16 = 66 - 16 = 50

Then, you get your final answer...

6. BC = 50

I hope it's right. Good luck ^^
