2.5.3 Journal Proofs of Congruence. I'm stuck on questions 5 and 6. Question 5: Using the previous problem, fill out the two column proof that ABD CBF. You may not need to use all the rows. Question 6. Are the truss triangles ADB and BFC congruent? Which postulate did you use for your proof? Which engineer was correct?

3 is greater then both of those numbers

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
