A certain middle school requires that every student participates in at least one of the two science fairs held during the year. If 195 of the 280 students participate in the school fair and 155 participate in the district fair, what percent of the students participate in both?

a reflection across the x axis and a 90 degree rotation left and right.

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )
