180-93=87..... Exterior angles of a triangle
Answer:
Step-by-step explanation:
140,000,,, 50,000 is estimated
Answer:like terms: 5x + -9x = -4x 6 + -2x = -12 + -4x Solving 6 + -2x = -12 + -4x Solving for variable 'x'.
Step-by-step explanation:
6 - 2x = 5x - 9x + 18 - 12 6 - 2x = -4x + 6 -2x = -4x 4x - 2x = 0 2x = 0 x = 0 / 2 x = 0.
Becouse k and n are 'neighbours' so their sum are 180
so k=180-42=138
