What is the perimeter of the triangle?​

Mathematics
2 answers:
Dmitrij [34]3 years ago

Answer:

19.24 cm

Step-by-step explanation:

Square the outsides of the triangle. 8 squared is 64 and 5 squared is 25.

A^2+B^2=C^2

c^2 is always the diagonal line.

a^2=25

c^2=64

Subtract 25 from 64 to find b^2

64-25= 39

Add all three together to get your perimeter.

The square root of 64 is 8, the square root of 25 is 5 and the square root of 39 is 6.24. Add 8, 5 and 6.24 together and you get the perimeter.

5+8+6.24= 19.24

Step-by-step explanation:

As you can see , angle B = 72⁰ by angle sum property

So AB = AC = 8 cm (isosceles property)

Perimeter = 8 + 8 + 5 = 21 cm

ehidna [41]
N = number of people = constant

number of people who have adopted the new technology: x(t) = x

number of people who have not adopted the new technology: n - x

proportionality constant: k

dx / dt = kx(1-x)

x(0) = 0 (this is at t = 0, 0 people have adopted the new technology)

Answer:

I believe the length would be <u>closer to 5 meters</u>. This so because, when looking at perfect squares, √30 is closer to √25 (which equals 5) than √36 (which equals 6).
