3x-4y=10
-20-x+2y=10 then -30+2y=x now plug this in the other equation:
3(-30+2y)-4y=10
-90+6y-4y=10
2y=100
y=50
a is SSS, c is SAS and d is ASA, all good congruent triangle theorems.
b is AAA, good to show similar triangles, not necessarily congruent triangles.

Answer:
50
Step-by-step explanation:
The upper left hand arc is also 130
The lower right hand arc is also x
A circle all the way around from some starting point is 360 degrees.
x + x + 130 + 130 = 360 Equation. Combine like terms.
2x + 260 = 360 Subtract 260 from both sides
2x = 360 - 260
2x = 100 Divide by 2
x = 100/2
x = 50
