Answer:
Step-by-step explanation:
radius = distance between (2,3) and (5,3) = √[(5-2)² + (3-3)²] = 3
2+2=2x+2
-2 to both sides
2=2x
Divide 2
X=1
You have to distribute so the correct answer would be 3s+21
The answer is <span>12^2=x^2+8^2-16x(cos(72°) </span>
<span>x^2-4.9443x=80 </span>
<span>(x-2.4721)^2=86.1115 </span>
<span>x-2.4721=±9.2796 </span>
<span>x=11.7517 </span>
<span>B=72°, b=12, c=8, a=11.8 </span>
<span>C=arcsin(8/12*sin(72°))=39.3° </span>
<span>A=68.7° </span>
