You divide 91/14 to get w=6.5.

Let's talk about basic distribution on equations.

You equation is 14w = 91. You need to find w

What it is essentially saying is, "What times 14  equals to 91?" The main way to find what w is is to first look at the equation:

14w is basically saying 14 times w. What you need to do is to isolate "w" by itself in one side. To keep it simple, we will keep the w in the left side.

Essentially, the next step is to divide 14 on EACH side. This is essential to do it on each side to make the equation still equal and be valid

What it would look like is this:
\frac{14w}{14} =  \frac{91}{14}

\frac{14w}{14}. The 14 cancels out to be 1, therefore w is resulted to be by itself. The other side is \frac{91}{14}. This simplifies to \frac{13}{2}.

The final result will be: w = \frac{13}{2} or 6.5 as a decimal

The other 2 angles of given right angles are 61.93° and 28.072°, if a triangle with side lengths 8, 15, and 17 is a right triangle by the converse of the Pythagorean Theorem.

Step-by-step explanation:

The given is,

                 Right angled triangle,

                 Side lengths are 8, 15, and 17  

Step:1

                The given triangle is right angle triangle by the converse of Pythagorean theorem, so the trigonometric ratio,

               Ref the attachment,

               For angle a,

                            ...................................................(1)

                 Where,  Opp - 8

                                Hyp - 17

                 From equation (1),

                                      

                                      = 0.470588

                                      (0.470588)

                                   a = 28.072°

                    For angle b,

                                  ...................................................(1)

                 Where,  Opp - 15

                                Hyp - 17

                 From equation (1),

                                      

                                      = 0.882352

                                      (0.882352)

                                   b = 61.93°

Step:2

          Check for solution for right angle triangle,

                        90 ° = Other 2 angles

                        90 ° = a + b

                        90 ° = 28.072° + 61.93°

                        90 ° = 90 °

Result:

          The other 2 angles of given right angles are 61.93° and 28.07°, if a triangle with side lengths 8, 15, and 17 is a right triangle by the converse of the Pythagorean Theorem.
