Answer is B.
it's parallelogram and opposite sides are congruent.
--------------------------
Answer:
8x10^-6
Because the decimal point must be moved left 6 places in order to be equal when multiplied by the whole number the 10 must be to the -6th
Answer:
Step-by-step explanation:

<h3>Given </h3>
<u>Kite WXYZ with:</u>
- XY = 3a - 5
- YZ = a + 11
- ∠W = 50°
- ∠X = 3b
- ∠Y = 70°
<h3>To find </h3>
<h3>Solution</h3>
<u>Since XY and YZ are congruent sides, XY = YZ</u>
- 3a - 5 = a + 11
- 3a - a = 11 + 5
- 2a = 16
- a = 8
<u>The angles Z and X are equal and the sum of 4 angles is 360°, therefore:</u>
- 3b + 3b + 50° + 70° = 360°
- 6b + 120° = 360°
- 6b = 240°
- b = 40°
<u>Correct option is the last one </u>
