Answer:
Option D
x = 27; m∠FDG = 62°; m∠GOF = 118°
Step-by-step explanation:
To solve this, we will need the help of the following laws of geometry:
1. We can see that the shape formed is quadrilateral. The sum of the interior angles of a quadrilateral = 360 degrees.
2. The angle between a radius and a tangent = 90 degrees. as a result of this, <OGD = <OFD = 90 degrees.
Once we have values for all the angles of the quadrilateral, we can set up an equation using the first rule mentioned above.
2x+8 + 4x+10 +90 +90 = 360 (Sum of interior angles of a quadrilateral = 360)
6x = 162
x=27 degrees
Now we have the value of x, we can find FDG and GOF as follows:
FDG = 2x + 8 = 2(27)+8 =62
FOG = 4x + 10 = 4(27)+ 10 =118
