Answer:
C. All trapezoids have exactly one set of parallel sides.
Answer:
2.7x10^7 or 2.70000000 I think
Step-by-step explanation:
Answer:
a^2+b^2=c^2
a^2=c^2-b^2
a^2=10^2-5^2
a^2=100-25
a^2=75
a=7.7cm
Step-by-step explanation:
Answer
Yes
Step-by-step explanation:
(8 roundtrips)(89 miles)(28 days) = 19,936
To solve the question we shall use the formula for the range given by:
Horizontal range, R=[v²sin 2θ]/g
plugging in our values we get:
500=[160²×sin 2θ]/10
5000=160²×sin 2θ
0.1953=sin 2θ
thus:
arcsin 0.1953=2θ
11.263=2θ
hence:
θ=5.6315°~5.63
