The ratio of perimeters is the same as the ratio of corresponding sides:
... (140 cm)/(56 cm) = 5/2
Answer:
10$ I think
Step-by-step explanation:
2*30=60
90-60=30
30/3=10
Let m = 10 and n = 2
We know:
y^2 = (m+n).m
y^2 = (10+2).10
y^2 = 120
y = √(120)
Then,
m^2 + x^2 = y^2
10^2 + x^2 = ( √( 120) )^2
100 + x^2 = 120
x^2 = 120 - 100
x^2 = 20
x = √(20)
x = √(4×5)
x = √(4) × √(5)
x = 2√(5)
I hope this has helped!
