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
