Answer:

They won £117 in total.

Step-by-step explanation:

There are two methods to solve the question.

  • Finding the total amount directly
  • Finding Dan's share and adding it to Colin's share

It is given that the ratio is 4:5

Let x be the share of Dan

The ratio between Colin and Dan's share will be 52/x and it should simplify to 4/5

\frac{4}{5} = \frac{52}{x}\\4x = 52*5\\4x = 260\\\frac{4x}{4} = \frac{260}{4}\\x = 65

The total amount will be:

Dan's\ share+ Colin's\ share = 52+65 = 117

Hence,

They won £117 in total.

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.
