Step-by-step explanation:
As all angles in a triangle add up to 180°
we can write:
(m+18)+(2m+28)+(3m+47) = 180
6m + 93 = 180
6m = 180 - 93
6m = 87
m = 87 / 6
m = 14.5
The first statement is true because 10 x 50 = 500
Yes they are correct good job
There is an understood decimal behind the 0. move the decimal two places to the left. making it .50. <span />
