Oh I took this ! first one is 36, and the second one is 18
They're perpendicular.
Both equations are in the form y=mx+b, where m is the slope and b is the y-intercept.
Perpendicular lines have opposite reciprocal slopes (ex: the opposite reciprocal of 5 is -1/5).
Parallel lines have the same slope, but different y-int.
The exact value of sin 5π/4 is 0. 0677
<h3>How to find the value</h3>
It is important to note that π = 3. 142
Let's find sin 5π
Substitute the value
sin 5π = sin (5 × 3. 142) = sin 15. 71
= 
Find the sine of the number
= 
= 
Thus, the exact value of sin 5π/4 is 0. 0677

A + 5 2/3 = 9
a + 17/3 = 9
move the 17/3 over to the other side by subtraction (will need to find a common denominator)
a = 10/3
Hope this helps
