Answer is 36.
20 * 80/100 = 16
20+16=36
Answer:
a=54.15 and b=14
Step-by-step explanation:
Sides are x,x,b
x is identical side
x is bigger than 3 times b by 2
x=3b+2
p=x+x+b
60=2x+b
x=3b+2
60=2(3b+2)+b
60=6b+4+b
60=7b+4
minus 4 both sides
56=7b
divide both sides by 7
8=b
sub back
x=3b+2
x=3(8)+2
x=24+2
x=26
legnths are
26in, 26in, 8in
well 7-6 is one then you'll find common demonstrators with the fractions then simplify them then subtract them to get 1 1/4
