10x+2x+13=145 angle of WIJ and HIW is equal to 145 degrees 12x+13=145 12x=132 x=11 angle of WIJ is 10x angle of HIW is 2x+13 to find angle of HIW, you plug in x=11 into 2x+13 and the answer and angle of HIW is 35 degrees.
12:00 to 1:30 , that is 90 minutes if 35 people enter each minute then it should be multiplied by the number of minutes that being said, 90 x 35 = 3,150 people are in the stadium at 1:30
