What is the perimeter of the triangle?​

Mathematics
2 answers:
Dmitrij [34]3 years ago
7 0

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

Using the distributive property write a numerical expression that is equivalent to 25+10
Diano4ka-milaya [45]

Answer: 5(5 + 2)

Step-by-step explanation: We will be using the distributive property to write a numerical expression that is equivalent to 25 + 10.

The expression 5(5 + 2) is an expression that uses the distributive property and is equivalent to 25 + 10.

5(5 + 2) is equivalent to 25 + 10 because all your doing when using the distributive property is multiply the number outside the parentheses by the numbers inside the parentheses. 5 x 5 = 25 and 5 x 2 = 10, which means 5(5 + 2) equals 25 + 10.
