A natural hazard is something that occurs in nature.
A tornado, a flood, and lightning are all examples of natural hazards.
Nuclear waste doesn't occur because of nature.
So the answer is..
Nuclear waste!
Answer:
A. 113°
Explanation:
opposite of the largest side is the largest angle
a=18 b=25 c=36
law of cosines
largest angle= arccos((a^2+b^2-c^2)/2ab))
largest angle= arccos((18^2+25^2-36^2)/2*18*25))
largest angle= arccos(-347/900)
largest angle= arccos(-0.38555555555)
largest angle= 1.96660618 rad
1rad × 180/π = 57.296
1.96660618×180/π=
112.678234078
Given a diagonal with the sides 10 and 15 units, the angle formed between them is 120.
to get the length of the longest diagonal we use the cosine rule which states that;
c^2=a^2+b^2-2abCos(C)
where a,b and c are the sides and C is the angle.
therefore let:
a=15,b=10,C=120,c=?to solve for the length C we shall substitute the values in our formula:
c^2=15^2+10^2-2*15*10 cos 120
c^2=225+100-300cos120
c^2=325-(300*(-0.5))
c^2=325-(-150)
c^2=475
getting the square root of both sides;
sqrt (c^2)=sqrt475
c=21.795
the since this is the opposite side to the largest angle, we therefore conclude that the longer diagonal of the parallelogram is 21.795 units
