Answer:
BCD
Step-by-step explanation:
You can easily find out by the points at the end of line. These points indicate that this is line segment.
Answer: It's not
Step-by-step explanation:
A perfect square is always , where .
Knowing this, we can square root 144x to get 12x. Square rooting 81 gets us 9. Unfortunately, if we multiply 12 and 9 together, then double it, we get 216, which is definitely not 200.
Therefore, the polynomial is not a perfect square.
Answer:
29
Step-by-step explanation:
all in all it is 180 so 61 + m (which is 90 because it is a right angle)=151
then 180-151=29
If you imagine cutting the field along the diagonal and throwing one piece away,
you have a right triangle left. Its legs are 50yd and 100yd, and you're asking
us for the length of the hippopotanoose.
We know that the answer is the square root of (the sum of the squares of the
lengths of the legs).
C² = A² + B² = (50)² + (100)² = 2,500 + 10,000 = 12,500 .
C = √(12,500) = <em>111.8 yards</em> (rounded)
Answer:
see explanation
Step-by-step explanation:
the error in the question is that
sec²x = ≠ , and
csc²x = ≠
have been used incorrectly in simplifying the expression
then
