What is the value of h?<br><br> h = 20<br> h = 35<br> h = 55<br> h = 70
Makovka662 [10]
The interior angles next to the 2h angles are congruent and each one measures 70 degrees. Since the interior angle is 70 degrees  the exterior angle is 110 degrees.
2h = 110
divide both sides by 2
h = 55

It would take an hour for plane A to meet plane B which is flying towards it. If the distance between them will be 200 miles aft
sammy [17]
Let a = speed of the plane A, and b = speed of plane B.
(Assume that the net effect of the wind is negligible.)
From the first sentence, the distance between A and B after each travels for 1 hour is a + b miles. From the second sentence, after 45 minutes, or 0.75 hour, the distance between A and B is 200 miles. Plane a has traveled 0.75a, while plane B has traveled 0.75b.
Hence a + b = 0.75a + 0.75b +200
==> 0.25(a + b) = 200.
==> a + b = 800.
Therefore planes A and B are 800 miles apart now.
