hey! the value of y is 57
The value of sinA in the triangle is 0.6. Then the correct option is A.
Trigonometry is the branch of mathematics that set up a relationship between the sides and angle of the right-angle triangles.
In the given triangle base is 8 and the perpendicular is 6 units. To calculate sinA we need hypotenuse and then use the Pythagorean theorem.
H² = P² + B²
H² = 6² + 8²
H² = 36 + 64
H² = 100
H = 10
The angle sinA is the ratio of perpendicular and hypotenuse.
sinA = P / H
sinA = 6 / 10
sinA = 0.6
Hence, the correct answer is option A.

Answer:
0.6
Step-by-step explanation:
Answer:
Equations are
J=j → (1)
L=$2.90+J=$2.90+j → (2)
Jess earn $20j in 20 hours
Step-by-step explanation:
Given that Laura earns $2.90 more per hour than her friend, Jess.
we have to write an equation to show Jess earns per hour.
As j represents hourly rate of Jess i.e
Jess earns $j per hour.
∴ J=j → (1)
As Laura earns $2.90 more per hour than her friend, Jess
⇒ L=$2.90+J=$2.90+j → (2)
Eq (1) and (2) are required equation.
we have to find how much Jess earn in 20 hours
Hours=20
∴ In 1 hr Jess earn $j
In 20 hrs Jess earn $ 20j
