Answer: Sin 23 = 2/5

Step-by-step explanation:

If cos 67 degrees is close to 2/5. That is, approximately,

Cos 67 = 2/5

Multiply the numerator and the denominator by 50

Cos 67 = 100/250

From trigonometry ratio,

Cos Ø = adjacent/hypothenus

Where the

Adjacent length = 100 cm

Hypothenus length = 250 cm

Po = opposite length = 100cm

If the degree = 23

The closest length will be

Sin Ø = Opposite/ hypothenus

Sin 23 = 100/250

Divide both the numerator and the denominator by 50

Sin 23 = 2/5

Can someone please help me solve for X i’m really confused and I really need help please
DochEvi [55]

Answer: x = 7

Step-by-step explanation:

sure thing! so, one angle is 34 degrees, and the other clear angle is 60 degrees. we know that because the angle on the lower shape matches that one. we then just add those, which comes out to 94 degrees. a triangle is 180 degrees, so we subtract 94 from that in order to figure out the total degrees in that last angle. that angle comes out to be 86 degrees. then, we subtract 2 in order to divide easily. we then divide 84 by 12, and we get 7. so, x = 7

У — 3x 4<br> у &gt; 4х +1<br><br> Anyone know the answe on how to solve this???
Katen [24]

Answer:

Unbounded, infinite number of solutions

Step-by-step explanation:

1. Graph each inequality separately

2. Choose test point to determine which side of line needs to be shaded

3. The solution will be the the area where the shadings from both inequalities overlap

Since, the overlap almost covers the 2nd and 3rd quadrants there are an infintite number of solutions

NEED HELP . GIVING BRAINLIEST

Answer:

There are 108 inches in 9 feet

Step-by-step explanation:

Well, two unit multipliers mean we have to convert through two units before we arrive at our final answer so we can convert from feet to yards to inches!

We know that 3 feet equal a yard, right?

So we can divide 9 by 3 to get the amount that 9 feet translates to in yards.

9/3 = 3!

So we are now done with our first conversion! Our second is going to be from yards to inches!

There are 36 inches in 1 yard so we should multiply 3 by 36 to get the amount in inches!

3*36 = 108!

Answer:

x=\frac{2\pm i\sqrt{6}}{2}

Step-by-step explanation:

-2x^2+4x=5\\\\-2x^2+4x-5=0\\\\x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\ \\x=\frac{-4\pm\sqrt{(4)^2-4(-2)(-5)}}{2(-2)}\\\\x=\frac{-4\pm\sqrt{16-40}}{-4}\\\\x=\frac{-4\pm\sqrt{-24}}{-4}\\ \\x=\frac{-4\pm2i\sqrt{6}}{-4}\\ \\x=\frac{2\pm i\sqrt{6}}{2}
