Answer:
Answer is 60 degrees.
Step-by-step explanation:
We know that in a right angled triangle if one leg is 1, and hypotenuse is 2,
then other leg = 
(By using Pythagorean theotrem)
Now consider a right angle triangle with hypotenuse 2 and one leg 1, and the angle between other leg and hypotenuse.
Since sin 30 = 1/2 we have cos 60= sin (90-60) = 1/2
Hence sin 60 = rt 3 /2
Using the above we get sin inverse of quantity square root of three divided by two is 60 degrees.
Answer:
So your answer is x=0.

Answer:
boys

Answer:
y = - 4/5x - 1 2/5 Step-by-step explanation:
(-3, 1) (1, -2)
-2 - (-1) / 1 - (-3) = -1/4
The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
