Please help! And also with a detail explanation so I can solve the next one on my own !

sin D = 0.25

Step-by-step explanation:

If ∠E = 90°, it means that the triangle is a right angle triangle.

Thus, hypotenuse will be the longest side which will be DC = 65

Since we are given CE = 16 and ED = 63, I have attached a diagram showing this triangle.

From the diagram, since we are looking for sin ∠D, we can say that;

sin D = opposite/hypotenuse

Now, opposite = CE = 16

Hypotenuse = CD = 65

Thus;

sin D = 16/65

sin D = 0.2462

Approximating to the nearest hundredth gives;

sin D = 0.25

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
