Answer:
rhombus
Step-by-step explanation:
Rhombus has that equiangular and is equilateral but I'm not entirely sure about this...
It's not clear what you're looking for.
If you want to find an angle whose terminal point involves a positive angle, then -120 degrees is equivalent to +240 degrees.
If you want the equivalent angle in radians, then:
-120 deg -π rad
-------------- = --------------- = - 2π/3 rad, or + 4π/3 rad.
1 180 deg
Recall that
Dividing both sides by cosh²(x) gives
Also, recall the identity
Then
Answer:
<h2>a) - a² + 5ab + 8</h2>
Step-by-step explanation:
3 pipes take 12 hours
⇒ In 1 hour, the 3 pipes can fill 1/12 of the pool
2 of the pipes take 18 hours
⇒ in 1 hour, the 2 pipes can fill 1/18 of the pool
In 1 hour, the third pipe alone can fill :
Time needed :
