If it’s correct, I’ll definitely mark brainliest

Answer 1

Answer:

x = 1

Step-by-step explanation:

• Triangle ABC and DEF are called congruent triangles.
• They follow the SAS rule (Side-Angle-Side), which means they have two equal sides, AC = DF and BC = EF, and one equal angle, angle C = angle F, that we know of
• So since they satisfy the SAS, we know the are basically the same size
• With that in mind, the corresponding sides will be equal, so side AB = DE
• $AB=DE\\2x-1=5x-4\\2x-(5x)-1+(1)=5x-(5x)-4+(1)\\-3x=-3\\x=1$
• Note: It is usually easier when you draw the triangles and see what you're working with
