<h3>
Answer: 54 degrees (third choice)</h3>
Explanation:
AB is a diameter of circle C. This leads to angle ACB being 180 degrees. By Thales Theorem (a special case of the inscribed angle theorem) we know that angle D is 90 degrees.
Therefore, triangle ADB is a right triangle. The acute angles (A and B) add to 90, and we can say they are complementary angles.
A+B = 90
36+B = 90
B = 90-36
B = 54 degrees
Since we know that the area is 100 and we are dealing with a square, that means that all sides are equal. We know that the sides are all 10 because 10*10= 100.
To find the perimeter, we add up all the sides: 10+10+10+10 = 40m
Answer:
rise is up and down run is side to side
Step-by-step explanation:
The answer:
to arrive at the similarity, the transformation must be as follow:
the small circle will be dilated for a specific scale factor,
the radius of X cirle is R= 6, and the radius of the small circle is r = 2
besides, two circles are similar if and only if R = r, (their radius ar equal)
therefore r = 2*k = 6, and from where k = 6 / 2 = 3 units
the answer is
<span>Translate the circles so they share a common center point, and dilate circle Y by a scale factor of 3.</span>
Do 340 ✖️0.20, and you'll get 68. Since that's 20% of 340, do 340 ➖ 68 and you'll get your final answer.
