In the following diagram, ABCD is a parallelogram. Is AC the bisector of angle BAD? Show calculations and explain

AC is not the bisector of angle BAD. AC made both sides a triangle and every triangles angles have to add to 180 degrees. So 115+30= 145 meaning angle DAC is 35 degrees. So AC cuts through BAD but one side is 30 degrees and the other is 35(DCB and DAB are the same angle…they both have to add up to 65 degrees)

yes

Step-by-step explanation:

in parallelogram ,<A=<C

<C=<D

then <D=115=<C=115

X+115+30=180TRIANGLE THEROME

X=35

so that,<A=65

<C=65

The expression for the length would be L = w + 7
