I really hope this can help you:)
We know that
mAB = 87°
<span>mED = 37</span>°
mEFA=mBCD
360°=mAB+mED+mEFA+mBCD
360=87+37+2mBCD------> mBCD=[360-87-37]/2----> mBCD=118°
therefore
m BCD=118°
m FA=m EFA/2-----> m FA=118/2----> 59°
m FA=59°
m DC=m BCD/2----> m DC=118/2----> 59°
m DC=59°
HB=GA------> HB=17
DB=2*HB----> DB=2*17-----> DB=34
EG=GA------> EG=17
the answers are
DB=34
EG=17
mBCD=118°
mFA=59°
mDC=59°
7.3x10^7 would be the answer
Given parameters:
Distance traveled = 1778miles
Average speed = 61.7 miles per hour
Unknown:
Time taken for the travel = ?
Speed is a physical quantity. It is the rate of change of distance with time.
It can be mathematically expressed as;
Speed =
The unknown here is the time taken;
Substitute the parameters and solve for it;
61.7 =
time taken = = 28.8hrs
The time taken is 28.8hrs
Since the value of the y-coordinates are the same for both points, the distance between the lines is the difference in x-coordinates, namely
distance = xh-xg = -12 - (-4) = -8, or 8 units in absolute value.
