Find the value of x. Show your work, congruent triangles

Nataly_w [17]

Answer:

x = 12

Step-by-step explanation:

130 + y = 180 {linear pair}

y = 180 - 130

y = 50°

3x - 6 +8x + 4 + 50 = 180 {Angle sum property of triangle}

3x + 8x - 6 + 4 + 50 = 180 {Combine like terms}

11x + 48 = 180

11x = 180 - 48

11x = 132

x = 132/11

x = 12°
