The answer is B because if you follow it starting from it AAS
Numerator
<span><span>cos<span>(<span>π/2</span>−x)</span></span>=<span>cos<span>(<span>π/2</span>)</span></span><span>cosx</span>+<span>sin<span>(<span>π/2</span>)</span></span><span>sinx</span></span>
now <span><span>cos<span>(<span>π/2</span>)</span></span>=0 and <span>sin<span>(<span>π/2</span>)</span></span>=1</span>
simplifies to : 0 + sinx = sinx

Answer:
Step-by-step explanation:
1) Reflection over 
2) The triangles are congruent by SAS, so when 
is mapped onto 
, because points 
and 
are corresponding, 
will correspond with .
3) Yes, because 
, so the triangles are congruent by SAS.
The given equation is :
Divide both sides by 5
Add 0.3 to both sides.
Multiply a on both sides.
Hence 
... Answer
