Answer:
To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
Step-by-step explanation:
Answer:
21 cm by 21 cm
Step-by-step explanation:
The formula for the area of a square is A = x^2, where x is the length of any one side of the square. Here,
441 cm² = x²
This actually has two roots: {√441, -√441), but since x must be positive here, to be a dimension of the square, we choose +√441, or +21.
The dimensions of the square are 21 cm by 21 cm.
the correct question in the attached figure<span>
we know that
</span>the probability
that a witness picks a particular person by chance-----> P=1/5
the probability
that all 7 witnesses would pick the same person-----> P=1/5^7=0.0000128
the answer is the option B 0.0000128
<span>There are a variety of problems in which the number of witnesses change, for example
</span><span>....find the probability that all
9 witnesses would pick the same person
</span>in this case, the probability would be-------> P=1/5^9=0.000000512<span>

There are 112 days in 16 weeks because if you multiply 7 times 16 you get 112 days.
