Find the value of y !!

y ≈18.8

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

y^2 +18^2 = 26^2

y^2 +324=676

y^2 = 676-324

y^2 =352

Taking the square root of each side

sqrt(y^2) = sqrt(352)

y is approximately 18.76

y ≈18.8

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
