How do i solve a given right triangle to find cos, sin, and tan. how do i solve for a missing adjacent side? (for example: imagine a right triangle with a, b, and c. 70 inches = opposite
12 feet = hypotenuse
x = adjacent. there is no given degree.

The steps to find cos, sin, and tan and missing adjacent side of a given right angle triangle is explained.

Solution:

Given, a right triangle with A, B, and C.  

Opposite side = 70 inches  

Hypotenuse = 12 feet = 12 12 inches = 144 inches

Adjacent side = "x" inches.  

We are not given angle, so we have to use the hypotenuse theorem

Hypotenuse theorem  means square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.

Substituting the values we get,

So, the adjacent side value is 125.8 inches approximately.

Hence the steps to find adjacent side is shown above

Now let us find cos, sin and tan

By substituting the required values, we can find cos, sin and tan

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
