Step-by-step explanation:

m/1 = ( 180 - 65 - 46 ) - 180

= 180 - 59 = 121

m/2 = 180 - 121 = 59

m/3 = ( 180 - 142 ) - 180

= 180 - 32 - 82

= 66

m/4 = 66

m/5 = 180 - m/2 - m/4

= 180 - 59 - 66

= 180 - 125 = 55

The sum of interior angles of triangles = 180°

Which of the following are coefficient

malfutka [58]

Answer:

2 and -3

Step-by-step explanation:

because a coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x).

so in 2x-3y+5, 2 and -3 are the coefficients.
