Answer:

Step-by-step explanation:

Since the two triangles are congruent, all their angles are as well.

So you can set 4y-10 = 3y+5 since they are the same angles.

Now solve the system by putting the y's on the left side and coefficients on the right side:

y=15.

Answer:

y=5

Step-by-step explanation:

Since the two triangles are congruent to each other. Angles R and X are congruent to each other.

Set the equations to each other.

4y - 10 = 3y+5

1.) Add 10 to both sides

4y= 3y +15

2.) Subtract 3y to both sides

3y=15

3.) Divide by 3 to get y by itself

y=5
