Answer: sin should be 10.8/ 13.7

Step-by-step explanation:

refer to sohcahtoa
this is because sin is opposite (10.8) over hypotenuse (13.7)
S Sin
O opposite
H  Hypotenuse

10.8 is opposite of the θ, 1.8 is not next to the θ, 8.4 is, so it is the opposite.
The hypotenuse is always the slanted line.

Which set of values for x makes the inequality 12−x<7 true
kozerog [31]

Answer:

\{x:x>5\}

Step-by-step explanation:

Given

12 - x < 7

Required

Values of x that make it true

First: solve the inequality.

12 - x < 7

Collect Like Terms

- x < 7-12

- x < -5

Multiply both sides by -1

-1 * - x < -5 * -1

x > 5 --- The inequality changes when multiplied by a negative value

So, the solution implies that the value of x is greater than 5 (i.e. 6, 7, 8..)

Hence, the set is:

\{x:x>5\}

Find the area of each figure. A = _ in²
Sholpan [36]

Answer:

1824in^2

Step-by-step explanation:

area of rectangle:

L x W = A

32 x 48 = 1539

area of triangle:

(L x W) / 2 = A

(48 x 12) / 2 = 288

add:

1539 + 288 = 1824in ^2

Find approximate solution for the equation in the interval 0&lt;_ x &lt;_ pi. round to three decimal places. tanx=5 sin x
timofeeve [1]

Answer:

d. 0, 1.369

Step-by-step explanation:

Given:

The equation is: \tan x =5\sin x................(0\leq x\leq \pi)

Adding -5\sin x on both sides, we get

\tan x - 5\sin x=0

Using the identity \tan x=\frac{\sin x}{\cos x}, we get

\frac{\sin x}{\cos x}-5\sin x=0

Factoring out \sin x, we get

\sin x(\frac{1}{\cos x}-5)=0\\\\\therefore \sin x=0\ or\ \frac{1}{\cos x}-5=0\\\\x=\sin^{-1} (0)\ or\ \cos x=\frac{1}{5}\\\\x=0\ or\ x=\cos^{-1} (\frac{1}{5})\\\\x=0\ or\ x=1.3694\approx 1.369(\textrm{Round to 3 decimal places})

Therefore, the solution of the given equation is either 0 or 1.369.

The correct choice is d.
