Answer: Y = -y - 12
Step-by-step explanation:
Answer:
roughly 12.56 units
Step-by-step explanation:
Since the perimeter of a circle is 2*pi*r, we can divide it by two or multiply by half in order to find the perimeter of a semicircle
half of the diameter is the radius, so 8/2 =4, r=4
Plug in what we know...
C=2*pi*4
Solve
2*3.14*4
25.12
divide by 2
25.12/2=12.56
12.56 units is the perimeter
Answer:
<em>Well, Your best answer will be is </em><em>45° </em><em>Because, Given two sides and the angle in between, we can calculate for ∠A using the sine law:
</em>
<em>
</em>
<em>b / sin B = a / sin A
</em>
<em>
</em>
<em>2.45 / sin 60 = 2 / sin A
</em>
<em>
</em>
<em>sin A = 0.707
</em>
<em>
</em>
<em>A = 45˚
</em>
<em>
</em>
<em>Therefore the answer is letter A: 45 </em><em>Good Luck! </em>
