Answer:
x ≈ 3.5 cm
Step-by-step explanation:
Using the sine ratio in the right triangle
sin23° = 
= 
= 
( multiply both sides by 9 )
9 × sin23° = x , then
x ≈ 3.5 cm ( to 1 dec. place )
Well, since it is asking for an average, we have to add
78+89+87+96=
350... then we divide by 4
which would be 87.5 which IS greater than 80 :)
and less than 90 :)
Answer:
im sorry what?
Step-by-step explanation:
i
-4x+9y+14 is the answer to the problem
Y=x/5
divide 5 on both sides, this is as far as you can simplify the equation with the information given
