Explanation:


\angle{DBC }=(5x+4)°


\angle{ A }=(2x-2)°


\angle{C }=(4x-6)°

we know that,


\angle{DBC}=
\angle{A}+
\angle{C}

According to the question,


\tt{ 5x+4=2x-2+4x-6 }


\tt{ 5x+4=6x-8 }


\tt{ 6x-5x=4+8 }


\bold{x=12 }

so,


\angle{C }=(4x-6)°=(4×12-6)°=(48-6)°=42°

Answer:

m<C = 42°

Explanation:

Given:

m<A = (2x - 2)°

m<C = (4x - 6)°

m<DBC = (5x + 4)°

Thus:

m<DBC = m<A + m<C (exterior angle theorem of a triangle)

(5x + 4)° = (2x - 2)° + (4x - 6)°

Solve for x

5x + 4 = 2x - 2 + 4x - 6

Collect like terms

5x + 4 = 6x - 8

5x - 6x = -4 - 8

-x = -12

Divide both sides by -1

x = 12

✔️m<C = (4x - 6)°

Plug in the value of x

m<C = 4(12) - 6 = 48 - 6

m<C = 42°
