Answer:
c ≈ 40
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° = 
= 
= 
( multiply both sides by c )
c × sin40° = 26 ( divide both sides by sin40° )
c = 
≈ 40 ( to the nearest whole number )
Answer:
Infinitely many solutions
Step-by-step explanation:
Simplify this
3 (y-2) = 3y-6
3 (y) + 3 ( -2) = 3y-6
3y-6=3y-6
Because these two equations are equal to each other, it is infinitely many solutions.
