Answer:
230.9 ft
Step-by-step explanation:
The side ratios of a 30°-60°-90° triangle are 1 : √3 : 2
In ∆ABC, BC = AB/√3 ≈ 115.47 ft
In ∆ABD, BD = AB√3 ≈ 346.41 ft
Then the length CD is ...
346.41 ft -115.47 ft = 230.94 ft
The distance CD is about 230.9 ft.
Subract what she rode already from total:
48-18 = 30
Divide by number of days:
30/4 = 7.5
she will need to ride 7.5 miles per day
x=11
sqrt(61)
4-(-1) = 5
-3-(-9) = 6
sqrt(5^2+6^2) = sqrt(25+36) = sqrt(61)
no.
a triangle can only have 180° in total but
60+60+63
=183°
Therefore a triangle can not have these three angles together.
