If sec
o =
1/cos o
Cos, what is cos
o?

Given: sec0=1, secX=1/cosX

we hv to find cos0,

We Have given:

SecX = 1/cosX

multiply cosX both side to get

secX × cos X =cosX /cos X

i.e, secX × cosX = 1

Relace X by '0', coz we hv to find for this angle

so equation becomes

sec0 × cos 0 = 1

given sec 0 = 1

i.e, 1 × cos 0 = 1

i.e, cos 0 = 1

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;
