Answer:
86 degrees
Explanation:
Alrighty, a simple 180-degree triangle, we can see that the two angles add up to 86, so what would make our angle G1 94 since 180-86 = 94, but we are tasked with finding the other side of that angle, let's call it G2, what should we do?
Since this is a flat 180-degree line, we do it again!
180-94 = 86 degrees
And there ya have it
Though, if you need the technical side, it's because a whole of a triangle is 180 degrees
Given that angles F is 58 and E is 28, we add those two up to find angle EGF. How to find EGF you ask? Simple- 180 degrees (Because it's a triangle) minus 86 (Added angles of E and F), that would equal 94.
Now, we are tasked with finding TGF. We do not have TGF but we have EGF. Learning that, we see the line ET, indicating that we have found ourselves a 180-degree line. What do we do with this line? We use it to calculate TGF with EGF
Since EGF is 94, we take the 180 - 94 to equal 86, and that is how you find TGF
