Sec theta - Csc theta / (csc theta)(sec theta)
Sophie [7]

Answer:

sin(x)-cos(x)

Step-by-step explanation:

\frac{\frac{1}{cos(x)} - \frac{1}{sin(x)}  }{\frac{1}{sin(x)} * \frac{1}{cos(x)}  }

Simplify the denominator:

\frac{\frac{1}{cos(x)} - \frac{1}{sin(x)}  }{\frac{1}{cos(x)sin(x)}  }

Simplify the numerator:

\frac{{\frac{2(sin(x)-cos(x))}{sin(2x)} }  }{\frac{1}{sin(x)} * \frac{1}{cos(x)}  }

Divide the fractions: <u>(a/b)/(c/d) = (a * d)/(b * c)</u>:

\frac{(-cos(x)+sin(x))*2cos(x)sin(x)}{sin(2x)}

Use the identity: <u>2cos(x)sin(x) = sin(2x):</u>

\frac{sin(2x)(-cos(x)+sin(x))}{sin(2x)}

Cancel out the common factor (sin(2x)):

-cos(x) + sin(x)

Simplify:

sin(x) - cos(x)

At the gym, Jasper was able to bench press 224 pounds, which was 7/8 of the weight that Balin was able to bench press. Which sho
Rzqust [24]

Answer:

The answer SHOULD be 7/8=224/x;256 pounds.

You may have made a mistake in inputting it here on Brainly. So look for the one that matches that.

Step-by-step explanation:

This is what we know:

Jasper = 224 pounds

Balin = x

Jasper = 7/8 of x

Now we make an equation for that:

(\dfrac{7}{8})(x) = 224pounds

To match the selections we will isolate 7/8 on one side of the equation:

\dfrac{7}{8}=\dfrac{224}{x}

Using ratio and proportion we can solve for what x is. Multiply 224 by 8 and divide it by 7. Or you can do it this way too:

\dfrac{7}{8}=\dfrac{224}{x}

(7)(x)=(224pounds)(8)

7x=1792pounds

x=\dfrac{1792pounds}{7}=256pounds

So x = 256 pounds
