If the student got a true statement, it is an identity
example, ending with x=x or 10=10 means it is an identity
if the student ended up with a false statement, there is no solution
example, 10=2

Answer:
x = 4
y = 4√3
Step-by-step explanation:
Reference angle = 30°
Hypotenuse = 8
Adjacent = y
Opposite = x
Recall: SOHCAHTOA
✔️To find x, apply SOH:
Sin 30 = Opp/Hyp
Sin 30 = x/8
x = 8 × sin 30
x = 8 × ½ (sin 30 = ½)
x = 4
✔️To find y, apply CAH:
cos 30 = Adj/Hyp
Cos 30 = y/8
y = 8 × Cos 30
y = 8 × √3/2 (cos 30 = √3/2)
y = 4 × √3
y = 4√3
Answer: 31 and 1/9
Step-by-step explanation:
d =29, for g=16,h=9
replace values of each number in equati/on:
d+g/h=29+19/9=(9*29+19)/9=( 261+19)/9=280/9= 31 and 1/9
