Find the value of x in the following diagrams (I drew them instead)

1)  51°      2)     _?_     3) 55 ⁰          4) 30°

Step-by-step explanation:

3) First you find out what is G which = 90⁰, And then add the 90 and 75.

Then we will make this equation : (90+75) - 360 ( because Angle Sum property = Sum of all angles from the inside = 360⁰)

Then we do that which will be = 185-360

                                                   =  175

The we plus all the x's = x + 2x

                                        = 3x

then our equation is =    3x= 175

                                   x = 175/3  (Because of Transposition )

                                    x= 55°

And Then we do add and multiply

Like This: x=55

               2x= 2x55 = 110°

1) First add 67 and 62

Then our equation= (67+62)-180 ( Because of Interior angle sum property of triangles = sum of all interior angles = 180°)

Then = 129 - 180

         = 51 °

And then because of opposite angle are equal so our x= 51° because our angle in the triangle above x = 51° so it will be equal opposite (hope you understand)

4) First add 2x+4x

    Our Equation= (2x+4x)=90° (be cause right angle = 90°)

                          =     6x=90              

                            x =90/6

                              x = 15°

So, 2x= 2 x 15 = 30°

     4x = 4 x 15 = 60°

2) Sorry I don't know the second one but i tried solving it but one favor can you please make another question for the second one in so i can answer there.

if x decreases by 4 then y increases by 10

step-by-step explanation:

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.
