Answer:
Yes
Step-by-step explanation:
It is a function since each x-coordinate is used only once. No two x-coordinates are equal. That makes it a function.
Answer: Yes
Answer:
4a)= 2.1m 4b)= 1.9 m 5)= 29.6º
Step-by-step explanation:
4a):
x is the opp
AB is the hyp
BC is the adj
thus,
sin32 = x/4
cross multiply, x= 4*sin32
x= 2.1196.......
x=2.1 m
4b).
x is the hyp
ac is the opp
bc is the adj
thus,
cos65=4.5/x
cross multiply, x= 4.5*cos65
x=1.9017....
x=1.9 m
5).
AB is the opp
bc is the adj
ac is the hyp
thus:
tanC= 2.1/3.7
C= tan^-1 (2.1/3.7)
C= 29.5778.....
C= 29.6º

Answer:
50
Step-by-step explanation:
62+68 is 130. 180-130 is 50
Answer:
x = 8
Step-by-step explanation:
The angles 75° and (5x + 35)° are vertical angles and congruent, thus
5x + 35 = 75 ( subtract 35 from both sides )
5x = 40 ( divide both sides by 5 )
x = 8
