Can you solve each equation to the nearest of a decimal, for 0<theta <360? 1) 4cos x+ √2=0 2）CSC x+3=0? Show all work

Answer 1

4cosx + sqr2 = 0

cosx = -sqr2/4

x = 180+69.3, 180-69.3

= 110.7 and 249.3

cscx + 3 = 0

cscx = -3

1/sinx =-3

sinx = -1/3

x= 19.5+180 = 199.5 degrees

or x=360-19.5 = 340.5 degrees
