Answer:
<em>< CDA = 140 degrees </em>
Step-by-step explanation:
For a rhombus, the sum of the interior angles is 360 degrees and also the opposite angles are equal i.e <ABC = <CDA and <BAD = <BCD
Given
<CAD = 20 degrees
<BCE = 20 degrees (based on geometry)
<BAD = <CAD + <BCE
<BAD = 20 + 20
<BAD = 40 degrees
Since <BAD = <BCD, then <BCD = 40 degrees
Get <CDA
<CDA + <ABC + <BAD + <BCD = 360
<CDA + <CDA + <BAD + <BCD = 360
2 < CDA + 40 + 40 = 360
2< CDA + 80 = 360
2< CDA = 360-80
2< CDA = 280
< CDA = 280/2
<em>< CDA = 140 degrees </em>
33+9=42. 42-40=2. These simple calculations show that two people must have raised there hands for both because the sum of the two groups who raised hands is two more than the amount of people in the actual class
, so corresponding sides occur in some ratio with one another. In particular, the order the vertices tells you that
Surface area = 10×6×2 + 14×6×2 + 10×14×2
=> 2×(60+84+140)
=> 2× 284
=> 568 m². <em><u>Ans.</u></em>
