Answer:
81°
Step-by-step explanation:
Opposite angles of a parallelogram are congruent. The sum of the two angles at B is the same as the value marked at D.
∠CBD = 139° -58° = 81°
_____
<em>Additional comment</em>
The angles at A and C are both 41°, the supplement of the one marked 139°.
-5t+5t+2+8-8
-5t+5t=0 or t
2+8-8=2
t+2 is the final answer
Ok, to check back on what the measure of a radian is, it is 57.3 degrees. So it would be about .78
radians
Use distance formula to find length of each side:
RQ = 5.39
RS = 4.47
ST = 3.61
TU = 4.12
UQ = 8.54
Total =26.13
Answer = 26.1 Units
