Answer:

Step-by-step explanation:

$\sum^{12}_{r=1} r^2 = \frac{12(12+1)(2*12+1)}{6}= A$

$\sum_{r=3}^{12}= \sum_{r=1}^{12} - (r_1+r_2)$

$r_1= 1^2$

$r_2= 2^2$

Plssss help <br> I need AC

Zolol [24]

Answer:

AC = 18

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos30° = $\frac{\sqrt{3} }{2}$ , then

cos30° = $\frac{adjacent}{hypotenuse}$ = $\frac{AC}{AB}$ = $\frac{AC}{12\sqrt{3} }$ = $\frac{\sqrt{3} }{2}$ ( cross- multiply )

2 AC = 12 $\sqrt{3}$ × $\sqrt{3}$ = 12 × 3 = 36 ( divide both sides by 2 )

AC = 18
