If sin x = 0.7, then you should use the trigonometric inverse:

x = sin^-1 (0.7)

On a graphing calculator, you press 2nd and then sin to get sin^-1.

Hello!

To find x, we multiply 0.7 by the arcsine with a scientific calculator as shown below.

sinx^{-1} (0.7)≈44.43

Therefore, x≈44.43

I hope this helps!

It costs $68 for 16 square feet of flooring. How much does it cost for 12 square feet of flooring?
belka [17]
We know that it costs $68 for 16 square feet of flooring. To find out how much it costs for 12, we first have to find out how much it costs for 1 square foot.
To find that, we would do $68 divided by 16, which is 4.25.
That means 1 square foot costs $4.25.
Then, we would multiply $4.25 by 12 to find how much 12 square feet costs.
$4.25 times 12 is 51.

So, it would cost $51 to have 12 square feet of flooring.

Answer:

The size is 37.5 degrees

Step-by-step explanation:

The total angle in the triangle is 180

Since the other two angles are congruent. it means that they are equal

Let us call each of the angles x

Mathematically,

x + x + 105 = 180

2x = 180-105

2x = 75

x = 75/2

x = 37.5
