So, i need with this question and will mark brainliest.

this an example not the answer i don't know the answer

E is between D and F.

Given: E is between D and F

Prove: DE = DF − EF.

 StatementsReasons

1.E is between D and FGiven

2.D, E, and F are collinear points, and E is on ¯DFDefinition of between

3.DE + EF = DFSegment Addition Postulate

4.DE = DF − EFSubtraction property of equality

2. If →BD divides ∠ABC into two angles, ∠ABD and ∠DBC, then m∠ABC = m∠ABC - m∠DBC.

Step-by-step explanation:

well what did you do it matters what you did : )

step-by-step explanation:

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
