Answer:
D. 180 ÷ 3 = m
Step-by-step explanation:
The sum of the angles in a triangle adds up to 180°.
Since equilateral triangles have 3 equal angles,
sum of the angles in the triangle= 3m
3m=180°
m= 180° ÷3
m=60°
Thus, 180÷3=m
Its about finding the equation of a circle from its general form equation:
x^2 + y^2 + 8x - 4y - 61 = 0
x^2 + 8x + 16 + y^2 - 4y + 4 = 61 + 16 + 4
(x + 4)^2 + (y - 2)^2 = 81
therefore the center is C(-4, 2), and the radius is 9
There is no illustration, so it is impossible to answer this question. I apologise.
<em>f = 16 females</em>
- Step-by-step explanation:
<em>f/m = 4/3 => m = 3f/4</em>
<em>f + m = 28</em>
<em>replace m</em>
<em>⁴⁾f + 3f/4 = ⁴⁾28</em>
<em>4f + 3f = 112</em>
<em>7f = 112</em>
<em>f = 16 females</em>
