In the diagram shown, chords ab and cd intersect at e. the measure of (ac) ̂ is 134°, the measure of (db) ̂ is (3x)° and the measure of ∠aec is (7x)°. what is the degree measure of ∠ aed?

Step-by-step explanation:

Twice the difference of the arc measures are equal to the angle AED.

2(134-3x) = 7x

Distribute

268 - 5x = 7x

Add the 5x to the other side.

268 = 12x

x = 22 1/3

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
