Question

АВ=32 см,АК на 10 см меньше КВ. Найти КВ.

Answer 1

x это KB

x-10 это AK

Тогда x+x-10=32

x=21

KB=21

Answer 2

Пусть АК=КВ, тогда АК=(32-10)/2=11 см;

КВ=11+10=21 см.

Answer 3

Let's solve the problem step-by-step. We know that AV = 32 cm and AK is 10 cm less than KV.

Let's assume that KV = x cm.

So, AK = x - 10 cm.

Now, we have two segments: AK and KV, and the total length of AV is the sum of these two segments:

AV = AK + KV

Substitute the given values:

32 cm = (x - 10 cm) + x

Now, solve for x:

32 cm = 2x - 10 cm

Add 10 cm to both sides:

32 cm + 10 cm = 2x

42 cm = 2x

Now, divide both sides by 2 to find the value of x:

x = 42 cm / 2

x = 21 cm

So, the value of KV is 21 cm.
