d = 8.5

Step-by-step explanation:

The following data were obtained from the question:

Angle D = 100°

Opposite D = d

Opposite E = e = 6

Opposite F = f = 5

Thus, we can obtain the value of d by using the cosine rule as shown below:

d² = e² + f² – 2ef Cos D

d² = 6² + 5² – 2 × 6 × 5 × Cos 100°

d² = 36 + 25 – 60 × Cos 100°

d² = 61 – – 10.419

d² = 61 + 10.419

d² = 71.419

Take the square root of both side.

d = √71.419

d = 8.5

Therefore, the value of d is 8.5

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
