Answer:
; 
Step-by-step explanation:
You can write two expressions that are in terms of 'x' and 'y'. This is a right triangle, so Pythagorean's theorem can be used. We can also use the angle to find the sine of 30 degrees.
<u>Pythagorean's Theorem:</u>
The values 'a' and 'b' are the two shorter sides of the triangle, while the value 'c' is the longest side of the triangle; the hypotenuse.



<u>Sine of the Angle:</u>
Sine is defined to be the opposite side divided by the hypotenuse. Let's take the sine of 30 degrees:




Plug this value of 'y' into the first expression derived from Pythagorean's theorem:






Use this value of 'x' to solve for 'y' in the expression from Pythagorean's theorem:






Answer:
42%, 3/7, .44
Step-by-step explanation:
what i would do is turn them all into decimals
3/7 is .4285
.44 is already a decimal
42% is .42
Each side is 52 cm. because equilateral triangles have equal lengths on each side. <span />
Answer:
K= 0.6 with the repeating 6.
the equation is y= 0.6x with the repeating 6
