You get the hypothenuse by doing √a²+b² = c
So....
Square both terms
x² + (3x+3)² = 625
x² + 9x² + 18x + 9 - 625 = 0
10x² + 18x - 616 = 0
x₁,₂ = (-b±√Δ)/2a
Δ = b²-4ac
You call a 10, b 18 and c -616
x1,2 = (-18±√18²-4*10*-616)/2*10
x1,2 = (-18±√324+24640)/20
x1,2 = (-18±√24964)/20
x1,2 = (-18<span>±158)/20
x1 = -18+158/20 = 140/20 = 7
x2 = (-18-158)/20 = -176/20 = -44/5
Pick the first solution
So one leg is 7 and the other is 3(7+1) = 3(8) = 24
Let's verify </span>√24²+7² = √576+49 = √625 = 25
Answer:
You will get 13 groups.
Step-by-step explanation:
324 / 24 = 13.5 So there are 13 groups with 5 left over. Hope this helps.
<span>2.3 seconds.
Let's assign the known values to the equation and solve for t.
h = 16t^2
86.4 = 16t^2
5.4 = t^2
2.323790008 = t
Rounding to the nearest tenth of a second gives 2.3 seconds.</span>
Answer: Hello, there! Sorry Im late But your answer is Below
30 sides Would be the correct answer
Step-by-step explanation:
t has 30 sides. The formula (n-2)×180 can be used to find the sum of the interior angles of ANY polygon where n is the number of sides in the polygon.
Hope this Helps!!
Have a great day!!!
