Use the commutative Property of Addition to add the last two terms first.
9 + (-17) + (-9) = -17
Hope this helps!! Good luck. :)
Answer:
350
Step-by-step explanation:
divide 100/4= 25
25*3=75 so width = 75 meters
perimeter= 2(l+w)
perimeter= 2(100+75)
perimeter= 2(175)
perimeter= 350
First off, let's notice that the angle is in the IV Quadrant, where sine is negative and the cosine is positive, likewise the opposite and adjacent angles respectively.
Also let's bear in mind that the hypotenuse is never negative, since it's simply just a radius unit.
