Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar.
Represent the measurement of angle B in the figure.
In the figure, angle A and angle D are complementary. The measurement of angle D is 45°. Complete the equation to solve for b, the
measurement of angle B.
180 =
+ (90 -
)+ b

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
