SOVA2 [1]

Answer:

35cm

Step-by-step explanation:

Given data

Length= 21cm

Width= 28cm

Diagonal= ???

Applying Pythagoras theorem

D^2= L^2+W^2

D^2= 21^2+28^2

D^2= 441+784

D^2= 1225

D= √1225

D= 35cm

Hence the diagonal is 35cm

CAN SOMEONE PLEASE HELP ME ASAP PLEASEEEE!!!

Answer:

11.4

Step-by-step explanation:

So we know that Triangle ACB is similar to Triangle EFD.

This means that their sides are proportional to each other.

We want to find x or side AB. To do so, we can set up a proportion.

The proportional side to AB is ED. Let's also use BC since we know its value. The proportional side to BC is DF. Thus:

$\frac{AB}{ED}=\frac{BC}{DF}$

Substitute x for AB, 3.8 for Ed, 15 for BC, and 5 for DF. Thus:

$\frac{x}{3.8}=\frac{15}{5}$

Reduce the right:

$\frac{x}{3.8}=\frac{3}{1}$

Cross multiply:

$x=11.4$

So, the value of x is 11.4

And we're done!
