Answer:

s = 120

r = 33

t = 33

Step-by-step explanation:

You are solving for the variables r & t & s. Note that it is given that the two parallelograms are congruent with each other.

Make sure that they are facing the same way. Note that DC ≅ GH, AD ≅HE, FE ≅ AB

Solve:

DC ≅ GH; 70 = s - 50

Isolate the variable, note the equal sign, what you do to one side, you do to the other. Add 50 to both sides;

70 (+50) = s - 50 (+50)

s = 70 + 50

s = 120

Solve:

AD ≅ HE

2r = 66

Isolate the variable, divide 2 from both sides:

(2r)/2 = (66)/2

r = 66/2

r = 33

Solve:

FE ≅ AB

t + 50 = 83

Isolate the variable, subtract 50 from both sides:

t + 50 (-50) = 83 (-50)

t = 83 - 50

t = 33
