Answer:
∠E = ∠F = 41°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
x + x + 98 = 180 ( subtract 98 from both sides )
2x = 82 ( divide both sides by 2 )
x = 41
Hence
∠E = ∠F = 41°
I don't know what you are asking for the first part of the question but 36+23+17 = 76
Hope this helped a little! :)
