Answer:

30 degrees   i hope this helps!   :)

Step-by-step explanation:

measure of angle Q is 90 degrees

measure of angle R is 60 degrees

measure of angle S is 30 degrees

side RQ is 1 unit

side RS is 2 units

side SQ is 1.732 units

Right Scalene Triangle

Side a = 1

Side b = 1.73205 = √3

Side c = 2

Angle ∠A = 30° = 0.5236 rad = π/6

Angle ∠B = 60° = 1.0472 rad = π/3

Angle ∠C = 90° = 1.5708 rad = π/2

C=90°B=60°A=30°b=1.732a=1c=2

Area = 0.86603

Perimeter p = 4.73205

Semiperimeter s = 2.36603

Answer:

30 degrees

Step-by-step explanation:

USE the sine function to determine S. Set up the equation:

sine(S) = 1/2 -->

S = Sine^-1(1/2) -->

S = 30 degrees

The total cost for two family cars was $71,1482 the cost of one car was $38,295 write an equation using a variable to represent
Harrizon [31]

Your 71,1482 doesn't make sense. But regardless,

let x = the other car's cost.

You know the total spent and the cost of one car. So logically, if you subtract the two you'd get the price of the second car.

You can do $38,295 + c = $71,1482.

Or $71,1482 - $38,295 = c.

Answer:

Please see the attached picture for the full solution.

*From the 4th line of the 1st image, you could also expand it using

(a +b)²= a² +2ab +b² and

(a -b)²= a² -2ab +b².

When squaring a fraction, square both the denominator and numerator.

➣(a/b)²= a²/b²

Finding values or<br> k(x) = x - 2<br> h(x) = x2 +1<br> (h + k)(2) =
Serjik [45]

Answer:

<h2>(h + k)(2) = 5</h2>

Step-by-step explanation:

(h+k)(x)=h(x)+k(x)\\\\\bold{METHOD\ 1:}\\\\k(x)=x-2,\ h(x)=x^2+1\\\\(k+h)(2)=h(2)+k(2)\\\\\text{Calculate}\ h(2)\ \text{and}\ k(2).\\\text{Put}\ x=2\ \text{to the equations of the functions}\\\\h(2)=2^2+1=4+1=5\\k(2)=2-2=0\\\\\text\\\\\text{Substitute:}\\\\(h+k)(2)=5+0=5

\bold{METHOD\ 2:}\\\\k(x)=x-2,\ h(x)=x^2+1\\\\(h+k)(x)=h(x)+k(x)=(x^2+1)+(x-2)=x^2+x-1\\\\(h+k)(2)-\text{put}\ x=2\\\\(h+k)(2)=2^2+2-1=4+2-1=6-1=5

What is the value for y in the following equation when x = -10?
nadezda [96]

Answer:

B.-38

Step-by-step explanation:

2x - 18 = y ...(1)

x = -10 (Given)

Now,

Put the value of x in equation (1) we get,

2(-10) - 18 = y

-20 - 18 = y

-38 = y

<em><u>y = -38</u></em>

Thus, the value of y is -38
