Question

I need help with geometry

Answer 1

B. x = 4

Explanation:

The two triangles have two congruent sides and a congruent angle. You can say ΔBAC ≅ ΔEDF because of SAS. Corresponding parts of congruent triangles are congruent, so you can say:

BC = EF

And we can substitute their values:

6x - 1 = 23

6x = 24

x = 4

Answer 2

B. 4
6x-1=23
+1 +1
6x=24
X=4
