<span>In a 30-60-90 triangle the side opposite the 30 degree angle is half the length of the hypotenuse.
The shorter leg is </span>the side opposite the 30 degree angle, therefore
the shorter leg = 30/2 = 15
<span>By the Pythagorean theorem
</span><span>the longer leg = </span>√(30² - 15²) = √(900-225) = √675 = 15√3 ≈ 25.98 units
I think the equation would be Y= 1x -4
7x-4=3x+ 8
-3x of both sides 4x-4=8
plus 4 to both sides 4x=12
12 divide by 4 = 3
hopeful that helps
Answer:
a) 
b) 
Step-by-step explanation:
<u>Coterminal angles</u> have the same terminal sides in standard position.
a) To find an angle between
and
, that is coterminal with
, we keep adding multiples of
until we get an angle within the specified range.
.
In some cases you would have to subtract in order to get the specified angle. That is when the angle given is positive.
b) This time we want to find an that coterminal with
radians.
We keep subtracting multiples of
until we get an angle measure within the specified range.
