how do i do that...
Mertsj
  • Mertsj
Substitute the know values, cross multiply and solve.

  • Mertsj
You are given sin P, sin R and r
anonymous
  • anonymous
so i have 0.3/p = sinP/10
Mertsj
  • Mertsj
sinP is given to be .3 Replace sin P with .3

so 10x0.3= 3 what does 0.4 x p = 0.4p ?
Mertsj
  • Mertsj
yes
anonymous
  • anonymous
great !
anonymous
  • anonymous
so for the answer do i just put 0.4p?
Mertsj
  • Mertsj
To solve this equation: 3=.4p Divide both sides by .4
anonymous
  • anonymous
okay. 0.4/3 = 0.13 3/0.4 = 0.75
anonymous
  • anonymous
0.4/0.4 = 1
Mertsj
  • Mertsj
Better check your decimal point
anonymous
  • anonymous
7.5
Mertsj
  • Mertsj
yes
anonymous
  • anonymous
so is 7.5 my answer?
Mertsj
  • Mertsj
yes
