Answer:
a)60°
b)BD=10
c)AB=20
d)100√3
Step-by-step explanation:
B
let's BD be x
according to the question
<h2>therefore</h2><h3>BD=10</h3>
c)
according to Pythagoras theorem
a²+b²=c²
c=√a²+b²
c=√10²+(10√3)²
c=√100+300
c=√400
c=20
D)
<u>the</u><u> </u><u>two</u><u> triangles</u><u> are</u><u> congruent</u>
so AC=2(10√3)
=20√3
as we know
area of a triangle =
½bh
=½×20√3×10
=10√3×10
=100√3

Plane averaged 88mph with the wind and 44 against the wind. the average of these two averages is 66 mph. plane speed in still air is 66 and the wind speed was 22 (88-22=66 and 44+22=66)
