Answer:
The solution for x that I got is 7.6.
When substituted for x for the two equations, the angle measures are:
86, 38.4, and 55.6.
86 degrees is the largest angle measure.
Sin(2θ)+sin(<span>θ)=0
use double angle formula: sin(2</span>θ)=2sin(θ)cos(<span>θ).
=>
2sin(</span>θ)cos(θ)+sin(<span>θ)=0
factor out sin(</span><span>θ)
sin(</span>θ)(2cos(<span>θ)+1)=0
by the zero product property,
sin(</span>θ)=0 ...........(a) or
(2cos(<span>θ)+1)=0.....(b)
Solution to (a): </span>θ=k(π<span>)
solution to (b): </span>θ=(2k+1)(π)+/-(π<span>)/3
for k=integer
For [0,2</span>π<span>), this translates to:
{0, 2</span>π/3,π,4π/3}
-2 (-30) - 3y = 42
60 - 3y = 42
-3y = -18
y = 6
Answer:
30 cm
Step-by-step explanation:
2 * 15: 5 * 15
30:75
3/10 in
<span>1 in =(1/12)ft </span>
<span>1 ft =(1/5280) mi </span>
<span>3/10 in=3/10*(1/12)*(1/5280) mi </span>
