Answer:

x = 180 - (31 + 40)

Step-by-step explanation:

Note that the angle of a straight line has a measurement of 180°

31 + x + 40 = 180°

Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. Subtract 31 and 40 from both sides.

x + (40 + 31) (- (40 + 31)) = 180 (- (40 + 31))

x = 180 - (40 + 31)

Ostrovityanka [42]

Answer:

RM3,500

Step-by-step explanation:

Salary=RM375 per week

5% commission per week

If she target a minimum of RM 550.

Let x=minimum Sales

RM550=RM375 + 5% of x
