The diagram represents part of the exterior of the Bow Tower in Calgary, Alberta, Canada. In the diagram, triangle ABC and triangle CBD are equilateral triangles. Find the measure of angle BAE.

555.99.

step-by-step explanation:

hope this

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

ratio is 2 : 9

the answer is three

13.5 : 3

7 is the median   7.875 is the mean
