C. Infinitely many of solutions
<em>x = 9</em>
<em>y = 0</em>
- Step-by-step explanation:
<em>y = -2x + 18 </em>
<em>4y - x + 9 = 0</em>
<em />
<em>4(-2x + 18) - x + 9 = 0</em>
<em>- 8x + 72 - x + 9 = 0</em>
<em>- 9x + 81 = 0</em>
<em>81 = 9x</em>
<em>x = 81 : 9</em>
<em>x = 9</em>
<em />
<em>y = - 2×9 + 18</em>
<em>y = - 18 + 18</em>
<em>y = 0</em>
Answer:
= 2√3 m or 3.464
Step-by-step explanation:
Using the sine,
sin(60”) = x / 4 multiply both sides by 4
4 sin (60°) = x
4 * √3 / 2 = x
x = 2√3 m
slant height =2√3 m
