Here shall use the cosine rule:
let the length of the first diagonal be d;
thus
d²=8²+6²-2*6*8cos55
d²=64+36-96cos55
d²=44.93666211
d=6.7035
We know that two adjacent angles of parallelogram are supplementary, so since 180-55=125°, the length of the second diagonal d', we shall have:
d'²=8²+6²-2×8×6cos 125
d'²=64+36-96cos125
d'²=155.0633379
d=12.45244
Answers: (6.7035,12.45244)
You add the opposite of -28, which is just 28.
-28 + 28 = 0.
Yes, it has an even exponent/only even exponents
Answer:
Negative
Step-by-step explanation:
On the basis of mathematical theory, the chance of occurrence of any event is called theoretical probability.
For example if we toss a coin then the probability of a head and a tail is half half i.e 0.5.
But the probability calculated by repeated experiments and examine the outcomes are called experimental probability.
For example if we toss a coin 20 times and got 9 times head and 11 times head then the probabilities are given by

These probabilities are different what we got in case of theoretical probabilities.
