Step-by-step explanation:

base=5m

height=12

Pythagoras formula A2+b²=c2

so 12²+5²

144+25=169

so

√169=13m

Answer: 3 wires of 13 m =39m

Base side = 5m

Vertical side = 12m

Hypotenuse = length of one wire.

5^2 + 12^2 = Hypotenuse^2

Hypotenuse = 13m

3 wires of 13m length = 39m

The sum of 5 times a number and 16 is 31.<br> What is the number? <br> Enter your answer in the box.
agasfer [191]

Answer:

I will do a step by step explanation to help you.

First, subtract 16 from 31 so you can simplify what you need to find. We will call the unknown number X. So 5x = 15

15/5 = 3 so X = 3

Lets plug in X

3 x 5 + 16 = 31

Makes sense!

Hope this helps

kirill [66]

Answer:

The answer is kite.

Step-by-step explanation:

Well, just looking at the definition of a kite, we can see that it lines up with Mr. Tesoro's description and drawing of the quadrilateral. A kite has one right angle that meets up witht two equal lines. The opposite pair of lines, that are much longer, don't meet up to be a right angle. The definitions line up, so there's your match; the anser is kite.

Solve this equation:
jek_recluse [69]

Answer:

b. All real numbers

Step-by-step explanation:

Simplify:

  • 5(x-2) = (15x+6)/(3) - 12
  • 5x - 10 = 5x + 2 - 12
  • 5x - 10 = 5x - 10
  • -10 = -10
  • 0 = 0

Since both sides are equal to each other, any value of x makes this equation true.
