Answer:
Step-by-step explanation:
<span> In a </span>regular polygon <span>all </span>sides have the same<span> length, therefore:
x</span>² + 8x - 52 = x² - 2x + 8
x² - x² + 8x + 2x = 8 + 52
10x = 60
x = 60/10
x = 6
Answer:
8r
Step-by-step explanation:
Answer:
y = 8 √3
x = 4 √3
Step-by-step explanation:
y sin 60 = 12
y (√3/2) = 12
y = 8√3
y cos 60 = x
(8√3) ÷2 = x
x = 4 √3
