We are looking for the hypotenuse in this right triangle. The reference angle is 41 degrees. We have that angle and the side that is opposite that angle, 22, so the trig identity that we will use that relates the side opposite to the hypotenuse is sin. Our ratio would be set up like this: $sin(41)= \frac{22}{xy}$ . Solving for xy we will have $xy= \frac{22}{sin(41)}$ , choice D from above.

Find x and y please!!! I need help!!

jonny [76]

Answer

Step-by-step explanation:

(15x-8y)=52

180=90+52+x

x=38

System of equations:

15x-8y=52

6x+14y=38

y=-6.5+15/8x

6x+14(-6.5+15/8x)=38

6x-91+26.25x=38

32.25x=129

x=4

15(4)-8y=52

60-8y=52

-8y=-8

y=1

x=4

The smartest person can only help with the method please help <br> 3 1/4 divided by 2

nevsk [136]

Answer:

13/8 = 1 5/8

Step-by-step explanation:

first make 3 1/4 into an improper fraction

3 1/4 = (3*4+1)/4 = 13/4

13/4 /2

we know that dividing by a number is multiplying by its reciprocal, so

(13/4)/2 = 13/4 * (1/2)

multiply the numerators together, and multiply the denominators together

13/4 * (1/2) = (13*1)/(4*2) = 13/8 = 1 5/8

What is the answer ti 3\4 × g = 5/8

gladu [14]

For this case we have the following expression:

$\frac {3} {4} g = \frac {5} {8}$

We clear the value of the variable "g", for this:

We multiply by 4 on both sides of the equation:

$4 * \frac {3} {4} g = \frac {5} {8} * 4\\3g = \frac {20} {8}$

We divide by 3 on both sides of the equation:

$\frac {3g} {3} = \frac {20} {8 * 3}\\g = \frac {20} {24}$

We simplify:

$g = \frac {10} {12} = \frac {5} {6}$

Answer:

$g = \frac {5} {6}$
