What are the missing angle measures in parallelogram rstum< r=70,m< t=110m< r=110,m< t=110m< r=110,m< t=70m< r=70,m< t=110

,

Step-by-step explanation:

we know that

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

so

----> equation A

-----> equation B

we have

substitute in the equation B and solve for m<R

-----> substitute in equation A

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
