Answer: fries-$3.20, burger=$5.79

Step-by-step explanation:

1. form equations for each person

2. set them up one below the other

3. solve for one unknown

4. plug in that answer into one of the equations to get the other unknown

(f=fries, b=burger)

 21.18=2b+3f

29.56=4b+2f

-2(21.18=2b+3f)

 29.56=4b+2f  

-42.36=-4b-6f

29.56=4b+2f

 -12.8=-4f

   3.2=f

21.18=2b+3(3.2)

21.18=2b+9.6

-9.6         -9.6

11.58=2b

 5.79=b

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.
