Answer:
1. DNK 2. RNX 3. DNX 4. KNA and DNE
Step-by-step explanation:
1. If the angles are vertical, then they are reflected across their vertex
2. If two angles are complementary then they will add up to be 90, or inversely, if two angles add up to be 90, then they are complementary.
3. Supplementary angles add up to 180 such as two angles along a straight line.
4. If two of the angles have a common vertex and share a common side they are called adjacent angles
The circumference of a circle can be found by applying the formula 3.14*diameter. To find the area of a circle requires you to use the equation 3.14 * r^2. A change in diameter will affect the circumference. The approximate diameter of the circle 87.14 meters. This means the equation is 1854.7749*3.14, making the approximate area of the circle 5823.99319 m^2. ROund if you need to.
Answer:
Exact form: x = + 7 sqaureroot 2
Decimal Form: x = 9.89
The answer is 2.9 x 10^-3. You can just divide 5.8 and 2. You get 2.9. After when ever you are Dividing exponents you have to subtract the power. So (-6)-(-3) is just -3. So when you put it together you get 2.9 x 10^-3
