Answer:
The slope of line is 0 given points (2,8)(7,8)
Step-by-step explanation:
We need to find slope of line given points (2,8),(7,8)
The formula used to find slope of line is: 
We are given:

Finding slope using formula:

So, the slope of line is 0
The answer is 3/5 because u need to find the missing side in order to find sin
Answer is the first one on left
3/8 divided by 4/5 is the same as 3 * 5 / 8 * 4 = 15/32 or 0.46875
AB∥CD and m∠4=85°.
so
<1 = 180° - 85°
<1 = 95°
Because AB∥CD so <5 = <1 = 95° (corresponding angles are equal)
Answer
<5 = 95°
