Triangle abc is an isosceles triangle in which ab = ac. what is the perimeter of △abc?

5 + startroot 10 endroot units

startroot 10 endroot units

10 + startroot 10 endroot units

15 units

Option C.

Step-by-step explanation:

Assume that the below figure attached with this question.

Distance formula:

From the below figure it is clear that the vertices of triangle are A(-1,6), B(-1,1) and C(2,2).

Using distance formula we get

Similarly,

The perimeter of △ABC is

The perimeter of △ABC is .

Therefore, the correct option is C.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
