Answer:
11:00 pm Wednesday
Step-by-step explanation:
Given
Current Time in San Francisco:
at 120 deg W
Required
Determine the current time at Miami at 75 deg W
First, we need to calculate the hours difference between San Franciso and Miami
Convert degrees to hours.
So:
The above is the time difference between San Francisco and Miami;
The time in Miami is then calculated as:
Hence, the time at Miami is: 11:00 pm Wednesday
This will solved using the concept of proportionality:
(height of the cliff)/(height of the pole)=(base of the cliff)/(length from base of pole to the rope)
thus, let the height of the cliff be x, plugging the values in the formula we obtain:
x/6=86/7
hence solving for x we get
x=(86×6)/7
x=73.71 ft
Answer:
Answer is 71.95°
Step-by-step explanation:
Cosine formula is
a^2=b^2+c^2-2bc(cosA)
cos A =b^2+c^2-a^2/2bc
if a= 119,b=94,c=173
cos A=94^2+173^2-119^2/2(94*173)
=8836+29,929-14,161/2(16,262)
=38765-14,161/32,524
=24604/32,524
=0.7564
cos A=0.7564
cos^-1=40.85°.that's for angle A.
Using the same formula
B=31.1°
C=180-(40.85+31.1)
C=180-71.95
C=108.05
Since angle on a straight line is 180
therefore x is 71.95
Also the sum of angles A and B
Answer:
This can't really be factored, but it can be expanded slightly.
(3x³)³ = 27x⁹
R = -2 :) hope this helps
