Answer:
The length of QS = 14 _________
Answer:
<h2><u>Supplementary</u></h2><h2><u>x = 34</u></h2>
Explanation:
- Supplementary angles: Angles that measure up to 180°
- Write an equation to find x
4x + 10 + x = 180
4x + x + 10 = 180
5x + 10 = 180
- Subtract 10 from both sides
5x + 10 - 10 = 180 - 10
5x = 170
5x / 5 = 170 / 5
x = 34
The solution to the problem is as follows:
<span>cos2A - cos4A = -2 sin(6A/2).sin(-2A/2) = +2 sin(3A).sinA
and
sin4A - sin2A = 2 cos(6A/2).sin(2A/2) = 2 cos(3A).sinA
Hence RHS = (cos(2A)-cos(4A))/ (sin(4A)- Sin(2A)) = sin 3A / cos 3A = tan 3A = LHS
