Since 2 of the right angled triangle are the same, we know we have an isosceles triangle. This means that the missing lengths are the same.
So we can do the following:
a² + b² = c²
x² + x² = 13²
2x² = 169 (collect the x values)
x² = 84.5 (divide both sides by 2)
x = √84.5
x = 9.2
So the length of one of the legs is 9.2
I think it is the 3rd one. Hope this helps!
40=10+2x where x is the number of dogs.
30=2x
x=15
Therefore she must walk 15 dogs
Hope this helps :)
F(x) = 3x²-6x+2
f(2) = ?
f(2) = 3.2²-6.2+2
f(2) = 3.4-12+2
f(2) = 12-12+2
f(2) = 2
A) 2✔
