You have x , x+7, and 7x-7. When you add those up and equal it to 180 you can get your x. X equals 20
So one angle is 20 degrees
The second angle is 27 degrees
And the third angle is 133 degrees.
<u>Answer:</u>
The answer D is correct.
<u>Step-by-step explanation:</u>
-x + y = 8 ⇒ ( 1 )
7x + 3y = - 16 ⇒ ( 2 )
y = 8 + x ⇒ ( 3 )
Let us take equation 2 and let us replace y with (8+x).
Let us solve and find the value of x.
7x + 3y = -16
7x + 3 ( 8 + x ) = - 16
7x + 24 + 3x = -16
10x + 24 = -16
10x = -16 - 24
10x = -40
<h3>
x = (-4)</h3>
And now let us find the value of y.
For that, let us use equation (3)
Here, we have to replace x with -4 to find the value of y.
y = 8 + x
y = 8 - 4
<h3>y = 4</h3>
Now we have to the answers in the form ( x , y )
Let us write.
( x , y ) ⇒ ( -4 , 4 )
