There is a trig identity called the sum of 2 angles for sin its<span>
sin(a+b)=sin(a)cos(b)+cos(a)(sin(b)
</span>
You will need to use it. So in your question split the 4x in 2 equal parts 2x and 2x
<span>
</span><span>sin(4x)=sin(2x+2x)
</span>Now using the expansion above you will get
<span>sin(2x+2x)=sin(2x)×cos(2x)+cos(2x)×sin(2x)
</span>And it will simplify to
<span><span>2sin(2x)cos(2x)
I hope this helps you! Good luck :)</span></span>
0.06x+0.09 (1200-x)=96
Solve for x
X=400 at 6%
1200-400=800 at 9%

Step-by-step explanation:
10/12=8.3333333 and 8.3333333*27.5=22.916666666 repeated
The Relationship between Angle H and Angle L is that they are Corresponding Angles. Corresponding Angles are angles that equal to each other and are on the same side of the tranversal.
Sorry I don't know the answer to the first one without numbers. Hope that helped!
