The triangles are similar.
Find the lengths x and y.

X = 10.8 cm
y = 7.6 cm
This is because shapes classified as similar are proportional meaning you need to find the scale factor to find the missing values. To do so you can take corresponding vales from the each triangle and divide;
16.8 / 5.6 = 3
This means the scale factor is 3 for the small to large triangle and 1/3 for the large to small.
So;
3.6 (3) = 10.8cm
22.8 (1/3) or 22.8 / 3 = 7.6cm

Where’s the problems ? ?

Hello!

the answer is:

the answer is:

why?

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
