Answer:
Step-by-step explanation:
Recall that . Therefore,
In any right triangle:
- The sine of an angle is equal to its opposite side divided by the hypotenuse of the triangle (o/h)
- The cosine of an angle is equal to its adjacent side divided by the hypotenuse of the triangle (a/h)
- The tangent of an angle is equal to its opposite side divided by its adjacent side (o/a)
From and , we know:
- 's opposite side is 1
- 's adjacent side is
- The hypotenuse of the triangle is 4
Therefore, the desired answer is .
Answer:
y = 2/3x + 8/3
Step-by-step explanation:
y = 2/3x + b
0 = 2/3(-4) + b
0 = -8/3 + b
8/3 = b
The answer is A the first choice
