Need help please and thank you
Georgia [21]

Answer:

y=5

x=20 degrees

K= 43 degrees

L=137 degrees

Step-by-step explanation:

aducent angles of parralologram add to 180 degrees

so (6x+17)+ (2x+3)=180

or 6x+17+2x+3=180

so 8x+20=180

and 8x=160

x=20 degrees

opposite sides of parralologram are equal so

6y-13= 32-3y

or 9y=45

and y=5

opposite angles are coonguent so

ang K= 2x+3

so K= 43 degrees

aducent angles of parralologram add to 180 degrees

so ang L+43=180

and L=137 degrees

The diagonal AC is drawn in parallelogram ABCD Which method can NOT be used to prove that AABC is congruent to ACDA?
diamong [38]

Answer:

B SSA

Step-by-step explanation:

Geometric proofs can be used to show that the two triangles are congruent using ASA, SAS and SSS.

However, there is no such thing as SSA in geometry because an angle and two sides can not show congruence of triangles. This is so because the angle is not an included angle.
