Delvig [45]

Answer:t=1

Step-by-step explanation:

16-2t=t+9+4t

Collect like terms

4t+2t+t=16-9

Combine like terms

7t=7

Divide both sides by 7

7t ➗ 7=7 ➗ 7

Which is equivalent to sin^-1(tan(pi/4)) ? Give your answer in radians.

aleksklad [387]

We are to find the value of $sin^{-1}(tan( \frac{ \pi }{4}))$

First we evaluate tan(π/4). The value of tan(π/4) is 1.

So,

$sin^{-1}(tan( \frac{ \pi }{4})) =sin^{-1} (1)$

sin(π/2) = 1
So,
$sin^{-1}(1)= \frac{ \pi }{2}$

Thus, we can write:

$sin^{-1}(tan( \frac{ \pi }{4}))= \frac{ \pi }{2}$ radians.

So, the answer to this question is π/2 radians.
