Question

3
4. If tan= 3/4
find the values of sec and cos O.​

Answer 1

Answer:

cos theta = 4/5

sec theta = 5/4

Answer 2

Step-by-step explanation:

tan=3÷4

tan=opposite ÷adjacent

opposite =3

adjacent =4

hypothenues =?

(hypothenues)^2=(opposite)^2+(adjacent)^2

(hypothenues)^2=3^2+4^2

(hypothenues)^2=9+16

(hypothenues)^2=25

hypothenues =spuare root of 25

hypothenues =5

sec=hypothenues÷adjacent =5÷4

cos=adjacent ÷hypothenues =4÷5
