Given that a room is shaped like a golden rectangle, and the length is 29 ft with the ratio of golden rectangle being (1+√5):2, thus the width of the room will be:
ratio of golden triangle=(length if the room)/(width of the room)
let the width be x
thus plugging the values in the expression we get:
29/x=(1+√5)/2
solving for x we get:
x/29=2/(1+√5)
thus
x=(29×2)/(1+√5)
answer is:
x=58/(1+√5)
or
byrationalizing the denominator by multiplying both the numerator and the denominator by (1-√5)
58/(1+√5)×(1-√5)/(1-√5)
=[58(1-√5)]/1-5
=(58√5-58)/4
Using pythagorean theorem:

Answer:
(b) 0 = Yes; 1-9 = No
Step-by-step explanation:
Among digits, 10% of 10 digits is a single digit. Any answer choice that suggests more than one digit be used for "yes" is not appropriate. A good choice is ...
0 = Yes; 1-9 = No . . . . . choice (b)
Answer:
1086.3 cm²
Step-by-step explanation:
surface are of sphere = πD²
SA = (3.14)(18.6 cm)^2
SA = 1086.3 cm²
