I think the answer is (7x-3)(7x+3)
Well if they part that has 70 degrees is congruent to any other side it is 70 + 70 which equals 140 and 360 which is a complete circle minus 140 is 220 the missing angels are there fore 70 and 220 or if the angle isnt congruent then the other sides must be so what plus itself on top of adding 70 will get us 360. lets find out what 220 in half is since 220 and 70 equals 360. 110 is 220 in half so the sides missing on this could be 110 110

Answer:
A
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos X = 
= 
= 
, then
∠ X = 
( ) ≈ 44° ( to the nearest degree ) → A
