150m - 100m + 47.750 = 50.500- 200m

m=11÷600

Step-by-step explanation:

150m-100m+47.750=50.5000-200m

collect the like terms

-50m+47.75=50.5-200m

move variable to the left side and change its sign

-50m+200m+47.75=50.5

Move constant to the right side and change its sign

50m+200m=50.5-47.75

collect the like terms(again)

150m=50.5-47.75

subtract the numbers

150m=2.75

divied both sides of the equation by 150

m=11÷600

solution

m=11÷600

alternative form

m=0.0183

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
