Help please =]<br><br> Solve system of equations using any method 2x-6y=8 and 2x-6y=3
dusya [7]
Let z be any number (like x would be)

if we set z equal to 2x-6y, then we get z = 2x-6y

The system 

2x-6y = 8
2x-6 = 3

turns into this new system

z = 8
z = 3

but z is a single number. It can't be both 8 and 3 at the same time. So there are no solutions

Find the value of p and q
Ira Lisetskai [31]

Answer:

The answer to your question is p =  27.7      q = 29

Step-by-step explanation:

Process

1.- Calculate the value of all the angles of the triangle

The angle of 50° and the one to the right are supplementary

                                   x + 50 = 180

                                   x = 130°

- The sum of the internal angles in a triangle equals 180°

                     30° + y + 130° = 180

                              y = 180 - 130 - 30

                              y = 180 - 160

                              y = 20°

- The angle of the right triangle

                     50 + 90 + z = 180

                              z = 180 - 90 - 50

                              z = 40°

If sum up the superior angles 20 + 40 = 60°, then the biggest triangle is a 30-60-90

2.- Calculate q using the trigonometric function tangent

                        tan Ф = q / 55

solve for q

                        q = 55 tan 30

                         q = 28.9 ≈ 29

3.-  Calculate the hypotenuse of the biggest triangle

                       h² = 55² + 29²

                       h² = 3866

                       h = 62,12

4.- Use law of sines to find p

                     \frac{p}{sin 20} = \frac{62.12}{sin 130}

solve for p

                       p = \frac{62.12 sin 20}{sin 130}

                       p = 27.74
