Given that triangle LMN has side lengths of 18.5 inches, 10 inches, and 15.5 inches, prove triangle LMN is a right triangle. explain

Hypotenuse^2 = opposite^2 + adjacent^2

Explanation:

The diagram of the triangle has been attached to the solution.

Side length of the triangle: 18.5, 15.5, 10

To prove a right angle triangle, we would apply Pythagoras theorem

Hypotenuse^2 = opposite^2 + adjacent^2

Hypothenus is the longest side of a right angle triangle

Opposite is the length facing the angle theta at the base. Also referred to as the perpendicular

Adjacent is the base

Hyp^2 = opp^2 +adj^2

Hyp^2 = 18.5inches , opp= 15.5inches, adj= 10 inches

Hyp^2 = 18.5^2 = 342.25

opp^2 +adj^2= 15.5^2 + 10^2

= 100+240.25 =340.25

342.25 is not equal to 340.25

Since Hyp^2 is not equal to (opp^2+adj^2), it is not a right-angled triangle.

Except there is an error with the figures in the question, the lengths given in the triangle would not give a right angle triangle.

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
