Because m<7 and m<6 share a vertex and doesn’t share any common sides and they are across from each other which means they are vertical and vertical angles are congruent
7/12 - 3/12 = 1/3 Simplify each fraction if possible. Same denominator? YES! 7 - 3 = 4 Since they have the same denominator, you just subtract the numerators. Then simplify 4/12 4/4= 1 12/4= 3 Answer: 1/3 Hope that helps!
We can use the ratios for special triangles (see the attachment below). We'll be using the 45-45-90 triangle. We notice that side BC is equal to , and side AC (x using the special right triangle) is equal to 16. We can therefore say that side BC is equal to ft
