One leg in a right triangle is 11 ​m, and the hypotenuse measures 11√2 m. Find the length of the other leg.
ipn [44]

Answer:

\boxed{11m}

Step-by-step explanation:

Method #1: 45-45-90 Triangle

You can use the rules for a 45-45-90 triangle. These are:

→ Each 45-45-90 triangle is a right triangle with two additional 45° angles.

→ The triangle will have 2 legs, <em>x</em>, and one hypotenuse, <em>x</em>√2.

Therefore, because the problem gives values for one leg and the hypotenuse, the value for the one leg is equal to the value for the unsolved leg.

Method #2: Pythagorean Theorem

You can use the Pythagorean Theorem to solve for a missing side in a triangle. Please note, however, that the Pythagorean Theorem only works on <u>right</u> triangles.

The Pythagorean Theorem is defined as a^{2} + b^{2} = c^{2}, where <em>a</em> and <em>b</em> are both legs of the triangle and <em>c</em> is the hypotenuse.

Therefore, substitute the known value for <em>a</em>, 11, and the known value for <em>c</em>, 11√2. Then, evaluate each value to its power (except for <em>b </em>- it is unsolved) and simplify the equation with basic algebraic methods. Once your equation is down to b^{2}= ?, you should take the square root of both sides of the equation to get the value for <em>b</em>.

11^{2} +b^{2} =(11\sqrt{2} )^{2}\\121 + b^{2} = 242\\b^{2}=121\\b=11

Ship A receives a distress signal from the north, And ship B receives a distress signal from the same vessel from the southeast.
11Alexandr11 [23.1K]

The coordinates of Ship A and B are missing, so i have attached it

Answer:

The vessel in distress is located at the coordinate (1, 2)

Step-by-step explanation:

The coordinates attached shows that;

Coordinates of A are (3, 4) while that of B are (1, 1).

We are told that Ship A receives a distress signal from the north, And ship B receives a distress signal from the same vessel from the southeast.

Now, from the image attached, If we imagine extending the line of ship A that is getting distress signal from southeast and also same thing for ship B that is getting signal from north,we'll discover that the lines intersect at a point with co-ordinates of approximately; (1, 2)
