distance across a canyon Find RS

to determine the distance RS across a deep canyon. Joanna lays off a distance TR=582 yards. She then finds that T=32degrees50' and R=102degrees20' findRS? please show me the steps Thank U

Find all the angles ABC

a=4.0ft, b=5.0ft, c=8.0ft

given vector u with /u/=9 and direction angle of 30 degrees

Please show me the steps Tahnk You A. write u in the form B.Compute (2*u).v, where v=

Story problem: Find the plane's resulting speed?

A plane is heading due north with a ground speed of 405 mph. A 30 mph wind is blowing at a bearing of 48degrees. find the planes resulting speed.

Linear velocity

find the linear velocity of a point on the edge of a drum rotating 52 times per minute. The diameter of the wheel is 16.0in. Please show me all the steps thank you

Trigonometric Identities

use identities to find the exact values of each of the following: please show me the steps Suppose x=7*pi/12 a. sin x (using the difference identity) b. cos x (using the half-angle identity)

verify the following identity

sec0 * cos 2*0 = 2*cos0 - sec0

Evaluate complex expression

a. write 2 + sqrt(-16) in standard form b. (4+i)/(3-2*i)

Modular arithmetics

Show that z and iz have the same modulus. How are the graphs of these two numbers related?

vector operations please check this for me thanks

given vector v with /v/ = 4 and direction angle of 45 degrees, write v in the form a= 4cos 45 degrees= 4*.707=2.83 b= 4sin 45 degrees= 4*.707=2.83 vector v (a,b) becomes v(2.83, 2.83) compute (2*w).(u-v) where w = <-1, 0> 2(2<100)(5<60-4<45) 2*2<180*1.536<102.5 =6.144<282.5 or 6.144<-77.5degrees vector from equat ...continues
