Exterior angles of a polygon sum to 360

94 + 56 + 4.5x + x + 1.5x = 360

150 + 7x = 360

7x = 210

x = 30

Sum of interior angles of a pentagon is:

(5 - 2)*180 = 540

Sum of interior angles of a given pentagon:

72 + 3x + 89 + 99 + 2x = 540

5x + 260 = 540

5x = 280

x = 280/5

x = 56

Step-by-step explanation:

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
