A rhombus has sides of length 10 cm and one diagonal of length 12 cm. How long is the other diagonal, in cm?

The length of the other diagonal is 16cm

First and foremost, it should be noted that the length of the rhombus and the half diagonals will form a right angle. Therefore, 12cm will be divided by 2 which is 6cm.

Then, we'll use Pythagoras theorem which will be:

a² + b² = c²

6² + b² = 10²

36 + b² = 100

Collect like terms

b² = 100 - 36

b² = 64.

b =✓64.

b = 8cm

Then, the diagonal will be twice of b

= 2b = 2 × 8 = 16cm

Therefore, the other diagonal is 16cm.

16 cm

Step-by-step explanation:

Side of the rhombus and half diagonals form a right triangle

We have hypotenuse= 10 cm and one leg= 12/2= 6 cm

The other leg:

d/2= √10²-6²= √64= 8 cm

So the other diagonal is twice as 8 cm leg, d= 8 cm * 2=  16 cm

The answer is 109 times per second

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
