QUIZ: Isosceles and Equilateral Triangles
What is the length of BC?
X + 9
2x - 8
Enter your answer in the box
units
X
В

Actually Welcome to the Concept of the Isosceles triangle,

for a isosceles triangle,

AC = BC,

so we get as,

x+9 = 2x -8

9+8 = 2x-x

=> 17 = x

hence the length of BC is 17 units.

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
