Given the side lengths, determine whether thr triangle is acute, right, ovtuse, or not a triangle:
DaniilM [7]

Answer:

1) If sum of the two smaller sides of a triangle is greater than the third longer side, then its a triangle.

<h3>In our case, 20 + 23 > 41. Hence its a triangle .</h3>

Use the side lengths to classify the triangle as acute, right, or obtuse. Compare the square of the length of the longest side with the sum of the squares of the lengths of the two shorter sides

2) Square root of sum of the squares of the two smaller sides is equal to the third longer side, then its a right triangle.

In our case,

√20^2+23^2≈30.4795<41.

<h3>Hence not a right triangle.</h3>

Since the sum of the squares of the two shorter sides is < the square of the longer side, its an obtuse angle triange

If mike read 30 pages an hour how long will it take him to read 1225 pages
Gnesinka [82]

Answer: 2450 min or 40hr and 50 min

Step-by-step explanation:

We can use a proportion to set up this equation.

\frac{30 pages}{60 min} =\frac{1225 pages}{x min}

We cross muliply so get our equation.

30x=1225(60)\\

30x=73500

x=2450 min

It took Mike 2450 min to read 1225 pages. We can also use a proportion to write this in hours

\frac{60min}{1hr} =\frac{2450min}{x }

60x=2450

x=40 hr 50 min
