The distance Jada is from starting point will be found using the cosine formula:
c²=a²+b²-2abCos C
a=200, b=90, C=70°
thus plugging in our values we get:
c²=200²+90²-2×200×90×cos70
c²=40000+8100-36000(0.3420)
c²=35788
hence
c=189.1772 m'
therefore the distance Jada is from the starting point is 189.1772 m
Alright here we go...
<u>(-18) + (-15) - 23</u>
-33 - 23
= -56
<u>15-18+23</u>
-3 + 23
= 20
so I don't know how you want me to compare it but,
(-18) + (-15) - 23 < 15-18+23
