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!

Looking for the answer for problem number eight zoom in if needed
Law Incorporation [45]

For this, we will be using Triangle Angle Sum Theorem (all interior angles in a triangle add up to 180°) for Triangle BCD. Since Angle CBD and BDC are congruent to each other and Angle BDA, we can solve for those two angles to get that angle. Our equation will look like this: 180=35+2x

Firstly, subtract 35 on both sides of the equation: 145=2x

Next, divide both sides by 2 and your answer will be 72.5 = x.

Since Angle CBD and BDC are 72.5°, this means that Angle BDA is 72.5° as well.

swati won a Computer game that she played with matt. The sum of the scores was 754. The difference of there scores was 176. How
klio [65]

<u>Answer:</u>

Swati - 465 , Matt - 289

<u>Explanation:</u>

Let Swati's score be x and Matt's score be y.

Since Swati won the game her score is obviously higher.

We are given the sum and difference between their scores which we can write as , x + y = 754 and x - y = 176.

Solving these two equations by adding them we get 2x = 930 so x = 465. Substituting x in x - y = 176 we get y = 289

Thus Swati scored 465 points and Matt scored 289 points.

ehidna [41]
48= l*w
l= 8+w

To solve for width, substitute the value of l in the first equation so that everything is in terms of w.

Final answer: 48= (8+w)*w
