Answer:
40%
Step-by-step explanation:
5/5 - 3/5 (eaten) = 2/5
2/5 = 0.4
move the decimal point two spaces to the right
40%
4 sqrt32 + 4 sqrt48
= 4 sqrt2* sqrt16 + 4 sqrt3 * sqrt16
= 16 sqrt2 + 16sqrt3
= 16(sqrt2 + sqrt3)
Answer:
False
Step-by-step explanation:
I looked it up and I also remember it from school. The earth is closer to the sun in the winter. When i looked it up, heres what came up (from the library of congress): Many people believe that the temperature changes because the Earth is closer to the sun in summer and farther from the sun in winter. In fact, the Earth is farthest from the sun in July and is closest to the sun in January!
I'm pretty certain this is right, let me know.
Step-by-step explanation:
where does hj come form because a triangle only has 3 sides which Is ABC isn't it.
Step-by-step explanation:
law of cosine :
c² = a² + b² - 2ab×cos(C)
with c being the side opposite of C.
so, in our case
3² = 3² + 3²×3 - 2×3×3×sqrt(3)×cos(A)
0 = 3²×3 - 18×sqrt(3)×cos(A)
27 = 18×sqrt(3)×cos(A)
cos(A) = 27/(18×sqrt(3)) = 3/(2×sqrt(3)) =
= 0.866025404...
A = 30°
FYI : since it is an isoceles triangle, C = A = 30°.
and therefore B = 180 - 30 - 30 = 120°.
as the sum of all angles in a triangle is always 180°.
