Find the value of x. Round your answer to the nearest tenth sin x degree= 4/15

bulgar [2K]

Answer:

The value of x to the nearest tenth is, 15.5 degree

Step-by-step explanation:

Given that: $\Sin x = \frac{4}{15}$

To find the value of x;

Take inverse of sin both sides we have;

$\sin^{-1}(\sin x) = \sin^{-1}(\frac{4}{15})$

Simplify:

$x = \sin^{-1}(\frac{4}{15})$

Simplify:

$x = 15.46601015^{\circ}$

Therefore, the value of x to the nearest tenth is, 15.5 degree

Can some one solve these?!

ivolga24 [154]

All you need to solve these is a knowledge of the 3 main trigonometrical ratios.
I a right angled triangle where A is a non right angle:-

sin A = opposite / hypotenuse (hypotenuse is the sloping side)

cos A = adjacent / hyptenuse ( the adjacent side is the one the angle 'sits' on)

tan A = opposite / adjacent ( the opposite side is the one opposite the angle)

So to find the length of segment x in the first problem use

sin 61 = x / 50
then
x = 50*sin61 = 43.73

and to find the length of y:-

cos 61 = y / 50
y = 60 cos 61 = 24.24

The other questions can be solved in a similar way.

<h2>Steps:</h2><h3>A.</h3>

For this, plug 4 into the x variable (since 4 is in the x variable of g(x)) and solve as such:

$g(4)=\frac{1}{2}*4+5\\\\g(4)=2+5\\\\g(4)=7$
