What is the value of x?<br> 52°<br> 93°<br> (x + 3)<br> 78°
gizmo_the_mogwai [7]

Answer:

Step-by-step explanation:

Step One

Find the exterior angle connected to the 93 degree angle. It is also a supplement to 93. Supplementary angles add to 180. Call the exterior angle y

93 + y = 180          Subtract 93 from both sides

y = 180 - 93

y = 87

Step two

Add all the exterior angles. They equal 360

x + 52 + 87 + x + 3 + 78 = 360    Combine the like terms

Step 3

Solve the equation

2x + 220 = 360                            Subtract 220 from both sides

2x  = 360 - 220

2x = 140                                        Divide by 2

x = 70

I don't see that anywhere, but I'm pretty sure I'm right.
