Abcd - trapezoid is △aod ∼ △boc ? why ? is △aob ∼ △cod ? why ?

Step-by-step explanation:

Given: ABCD is a trapezoid.

Proof: Using the property of trapezoid that the bases of the trapezoid are parallel to each other.

From △AOD and △BOC, we have:

∠DAO=∠BCO (Alternate angles)

∠AOD=∠BOC( Vertically opposite angles)

Therefore, by AA similarity,

△AOD ∼ △BOC

Also, from ΔAOB and ΔCOD, we have

∠BAO=∠DCO (Alternate angles)

∠AOB=∠DOC(Vertically opposite angles)

Therefore, by AA similarity,

△AOB ∼ △COD

Hence proved.

answer: 0.95, d

step-by-step explanation:

first, you have to combine the percentages of costumers ordering pizza or salad. 25% (percent of salads ordered) plus 70% (percent of pizzas ordered) is equal to 95%. then, turn 95% into a fraction: 95/100. lastly, divide 95 by 100 and you will get 0.95, d.

the answer is 8

step-by-step explanation:

3.14 x 8x8
