On a coordinate plane, triangle a b c is shown. point a is at (negative 2, negative 4), point b is at (2, negative 1), and point c is at (3, negative 4). triangle abc is an isosceles triangle in which side ab = ac. what is the perimeter of triangle abc? 5 + startroot 10 endroot units 10 + startroot 10 endroot units 10 startroot 10 endroot units 50 units

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

the correct answer is b.

this is because an open circle means < or > & since the line goes left it is < -3.

the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1

hope that
