In parallelogram klmn, kn = 10, mn = 7 and mk = 50°

a. find the measures of the remaining angles of parallelogram klmn. justify each of the measures with a theorem.
b. find the measures of the remaining side lengths of parallelogram klmn. justify each of the measures with a theorem.

Part A)

Part B)

Step-by-step explanation:

we know that

In a parallelogram, the opposite angles and opposite sides are congruent, and consecutive angles are supplementary

Part A)

we know that

----> by opposite angles

----> by opposite angles

-----> by consecutive angles

we have

Find the value of m<L

therefore

Part B)

we know that

----> by opposite sides

----> by opposite sides

we have

therefore

1 1/7 hope i

step-by-step explanation:

8/7 = (1 * 7 + 1) / 7 = 1 + 1/7 = 1 1/7
