Answer:
10 cm
Step-by-step explanation:
If we assume that DC is parallel to AB, then triangle DOC is similar to triangle AOB.
However, even with this assumption, there is not enough information in the diagram to solve for DO. We would also need to know the length of CO. Then we could write a proportion:
DO / (DO + 20) = CO / (CO + 24)
Edit: OD is 2 cm shorter than OC. If we call x the length of OD, then the length of OC is x+2.
Putting this into our proportion:
x / (x + 20) = (x + 2) / (x + 2 + 24)
x / (x + 20) = (x + 2) / (x + 26)
Cross multiply:
x (x + 26) = (x + 2) (x + 20)
Distribute:
x² + 26x = x² + 20x + 2x + 40
x² + 26x = x² + 22x + 40
4x = 40
x = 10
So the length of DO is 10 cm.
Ok well since it says the product of a number and 6 is 44 more than twice the number. and from this they got 6x=44+2x because it SAYS THE PRODUCT OF A NUMBER U DON'T KKNOW WHAT THE NUMBER IS SO U USE A VARIABLE WHICH IS 6X THEY GOT = 44 FROM THE PRODUCT AND 2X FROM MORE THAN TWICE THE NUMBER AND TWICE IS 2 AND U DON'T KNOW WHAT THE NUMBER IS SO ONCE AGAIN USE A VARIABLE
HOPE THIS HELPED
Answer:
none of these

Answer:
<h2>1525.7 square meters, approximately.</h2>
Step-by-step explanation:
Notice that the radius is 28 meters, and the angle of the orange sector is 137°. However, the angle of the blue sector is:
360° - 137° = 223°
The area of a circular sector is
Replacing given values, we have
Therefore, the right answer is the second choice.
Four is the only number that has the same number of characters as its value in the English language
