Let x be the degree of angle a.
Angle b: 20+3x
Angle c: 55+x
We know that all angles add up to 180 degrees.
180=x+(20+3x)+(55+x)
180= 5x+75
180-75=5x
105/5=x
21=x
Angle a: 21 degrees
Angle b: 20+3(21) => 83 degrees
Angle c: 21+55 => 76 degrees

Answer:
52
Step-by-step explanation:
A(2) + B(2) = C(2)
10(2) + 24(2)
676 = C(2)
square root of 676
AC=26 BD=26
AC + BD
26 + 26 =
