2 and 1/5 is your answer.
decimal form=2.2
        
             
        
        
        
It’s D. 4 is the one next to X because that’s what is changing and -3 is the y intercept which comes after X
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
Let
x ----> the measure of one angle of the triangle
y ---> the measure of the second angle
z ----> the measure of the third angle
we know that
The sum of the measure of the interior angles in any triangle must be equal to 180 degrees
 -----> equation A
 -----> equation A
One angle of a triangle measures  10 degrees more than the second
 ----> equation B
 ----> equation B
 The measure of the third angle is twice the sum of the first two angles
 ---> equation C
 ---> equation C
substitute equation B in equation C

 ----> equation D
 ----> equation D
substitute equation D and equation B in equation A

solve for y

Find the value of x

Find the value of z

therefore
