What is the length of the altitude of the equilateral triangle below?​

Mathematics
1 answer:
ElenaW [278]2 years ago
5 0

Answer:

A

Step-by-step explanation:

the height a creates with half of the baseline (5) and a leg (10) a right-angled triangle, and we can use Pythagoras to calculate a.

c² = a² + b²

c being the Hypotenuse (the side opposite of the 90° angle, so in our case the 10 side).

10² = a² + 5²

100 = a² + 25

75 = a²

a = sqrt(75) = sqrt(3×25) = 5×sqrt(3)

Paul’s dog weighs 12 pounds more that Issac’s dog. Together they weigh 50 pounds. How much does Issac dog weigh ???
brilliants [131]

Answer:

Issac's dog weighs 19 pounds

Step-by-step explanation:

Let x be Issac's dog's weight

  1. Translate the problem into an algebraic expression: x + (x + 12) = 50
  2. Simplify: 2x + 12 = 50
  3. Subtract 12 from each side, so it now looks like this: 2x = 38
  4. Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = 19

I hope this helps!
