Answer:
-10 =v
Step-by-step explanation:
-13 = v/10 - 12
Add 12 to each side
-13+12 = v/10 - 12+12
-1 = v/10
Multiply each side by 10
-1*10 = v/10 *10
-10 =v

Answer:
85.6 cm^2
Step-by-step explanation:
The area of the central triangle bounded by each of the sides can be computed as ...
A = (1/2)r²sin(α) . . . . where α is the central angle, 360°/5 = 72°
There are 5 such triangles, so the area of the pentagon is ...
A = (5/2)(6 cm)²sin(72°) ≈ 85.595 cm²
The area of the regular pentagon of radius 6 cm is about 85.6 cm².
