Max constructed a scale model of the eiffel tower. the base area of the model is 0.25 square meters, while the base area of the actual eiffel tower is 15,625 square meters
what is the scale factor of the model?
a) 1: 625
b) 1: 250
c)250: 1
d)625: 1

1:250

Step-by-step explanation:

=

=250

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
