Given that tan? tan^2 0=3/8 what is the value of sec 0?

1.068.

Step-by-step explanation:

Use the identity

sec^2 O = 1 + tan^2 O

=  1 + (3/8)^2

= 1  9/64

= 73/64

so sec O =  √73/8

= 1 .068.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
