Find the resultant vector (in component form) created by adding →u and →v. →u+→v=   Suppose a third person begins pushing on the couch in the direction of the west wall of the room. How hard must she push so that the couch only moves towards the north wall?  _N    
Hint: for parts (a) - (c), your answer should be in the form "< #, # >" with two numbers inside the vector brackets. ​

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh

answer: (3,11) is your answer.
