triangle jkl is similar to triangle stu. what is the length of side lk?
a) 1.25 ft
b) 2.5 ft
c) 5 ft
d) 12.5 ft

we know that

If triangles JKL and STU are similar

then

the ratio of the corresponding sides are equals

so

we have

substitute

therefore

the answer is the option A

80 kilometers per hour is equal to 49.72 miles per hour.

Step-by-step explanation:

Given that the speed limit in some European cities is 80 km / h, to determine how many miles per hour is this, knowing that 1 mile is equal to 1,609 km, the following calculation must be performed:

1,609 = 1

80 = X

((80/1) x 1.609) = X

80 x 1.609 = X

49.72 = X

Thus, 80 kilometers per hour is equal to 49.72 miles per hour.
