Answer:

Step-by-step explanation:

The following ratios are equal in any circle

$\frac{arc}{circumference}$ = $\frac{angle atcentre}{360}$

Substitute in given values and solve for C, the circumference

$\frac{DE}{C}$ = $\frac{60}{360}$ = $\frac{1}{6}$

Cross- multiplying

C = 6DE = 6 × 52 = 312 cm → D

Lorico [155]

(3+11i)/(3+11i)=1

So that means you can multiply 6/(3+11i) by (3+11i)/(3+11i)

Then 6(3+11i)/1

= 18+66i
