Use the Pythagorean Theorem to find the missing
side of the right triangle.
2.5
Х
6

6.5

Step-by-step explanation:

6^2 +2.5^2 = x^2

36 + 6.25 = x^2

42.25 = x^2

6.5 = x

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
