Answer:

x = 3

y = 9

Step-by-step explanation:

\frac{x}{y} =\frac{1}{3}    →  ( 1 )

  • Use cross multiplication to the above equation.

3x = y   →  ( 2 )

x + y = 12 → ( 3 )

  • Now you can put 3x instead of y to equation (3) according to equation (2).

<u>Let us solve.</u>

x + y = 12

x + 3x = 12

  • And now you can solve the above equation and find the value of x.

4x = 12

Divide both sides by 4.

x = 3

  • Now we can put 3 instead of x to any equation here and find the value of y.

<u>Let us take equation ( 2 )</u>

3x = y

3 × 3 = y

9 = y

Hope this helps you :-)

Let me know if you have any other questions :-)

If triangle RST is within Quadrant 2 and csc T = 13/12, what is the value of cotT?
zhuklara [117]

Answer:

\boxed {cot T = -\frac{5}{12}}

Step-by-step explanation:

<u>Finding the missing side</u> :

  • x² = 13² - 12²
  • x² = 169 - 144
  • x = √25
  • x = 5

<u>Taking the cot value</u> :

  • cot T = adjacent / opposite
  • cot T = -5/12 (As cot is negative in Quadrant 2)
