Prove that tanx+secx/ secx (1+ tanx/secx)=1

elena-14-01-66 [18.8K]

Answer:

See below.

Step-by-step explanation:

We need to prove that tanx + secx = secx(1 + tanx / secx) (because their quotient = 1).

Taking the right side of the identity:

secx(1 + tanx / secx) Distributing the sec x we get:

secx + tanx = the left side.

Answer:

A x < 3

Step-by-step explanation:

$\frac{5(9-x)}{3} + 1 < 11$

$\frac{5(9-x)}{3} < 11 - 1$

$\frac{5(9-x)}{3} < 10$

5(9-x) < 10*3

5(9-x) < 30

9-x < 30/5

9-x < 6

-x < 6 - 9

-x < -3
