Solve for x. Round to the nearest TENTH of a degree. Type your answer as a single value (don't type "x=" or include any labels).
8090 [49]

Answer:

x = 36.9

Step-by-step explanation:

Use the sine function if you know the length of the opposite side and the hypotenuse. Plug your values into the equation: sine (x) = opposite ÷ hypotenuse. Say that the length of the opposite side is 6 and the length of the hypotenuse is 10. Divide 6 by 10, which is equal to 0.6. Now you know that sine (x) = 0.6 which is the same as x = sine^-1 (0.6).

Steps:

sin (x) = 6/10

sin(x) = 0.6

then we do sin^-1(0.6), which equals 36.869897645844 ° (degrees)

36.869897645844 ° (degrees) rounded to the nearest tenth is 36.9

so x = 36.9

Solve the following triangle for all missing sides and angles.
AlekseyPX

Answer:

Part 1: 100

Part 2: 29.19 (Rounded)

Part 3: 20.96 (Rounded)

Step-by-step explanation:

<u>Part 1</u>: Triangle Sum Theorem (All angles of a triangle add up to 180 degrees)

45 + 35 + A = 180

80 + A = 180

Move the constant to the other side

80 + A = 180

-80          -80

A = 80°

<u>Part 2:</u> Law of sines

\frac{a}{sin(100)} = \frac{17}{sin(35)}

Cross multiplication

sin(35)a = 16.7417318

Divide both sides by sin(35)

a = 29.18831866

<u>Part 3</u>: Law of cosines

b=29.19^{2}+17^{2}-2*29.19*17*cos(45) = 439.2809039

Square root the answer

\sqrt{439.2809039} =20.95902917

The sales tax rate is 6%. If c represents the cost of an item and s represents the amount of sales tax, which of the following e
Genrish500 [490]

Answer:

S = 0.06C   PLEASE GIVE BRAINLIEST

Step-by-step explanation:

s = 0.06c

If you input 5.00 is the cost of a pair of socks for C.

s = 0.06(5.00)

taxes paid on the socks will be:

5.00 x 0.06 = 0.30

So...

0.03 = 0.06(5.00)
