What is the length of side BC of the triangle?
Enter your answer in the box.
How many units??

BC= 24

Step-by-step explanation:

thhe triangle is isosceles

x+8 =2x-1

x -2x = -1 -8

-x = -9

x=9

substitute x=9 into the equation of BC

BC = 3x-3= 3*9 -3 = 27 -3 = 24

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
