Answer:
90%
Step-by-step explanation:
Complimentary means the same. And adding them together would equal 90. Just as you would divide 90 by 3, each individual angle would be equal to 30.
Given:
Point (7,12) is rotated 1260° counterclockwise about the origin.
To find:
The x-coordinate of the point after this rotation.
Solution:
If a point is rotated 360 degrees then its coordinates remains unchanged.
If a point is rotated 180 counterclockwise about the origin degrees, then
We know that,
After rotation the coordinates of points remains same, i.e., (7,12). So, after that (7,12) is rotated 180° counterclockwise about the origin.
The point (7,12) becomes (-7,-12) after rotation of 1260° counterclockwise about the origin.
Therefore, the x-coordinate of the required point is -7.
We use the tangent for this
tan 26 1 = opposite / adjacent = h / 205 where h = height of cliff
h = 205 tan 26 1 = 100 feet
Answer:
C.) 2×10²
Step-by-step explanation:
(Sun dia) / (Mars dia) = (1.4 x 10⁶ km) / (0.7 × 10⁴ km) = (1.4/0.7) × 10²
The ratio of diameters is about 2 × 10².
_____
The applicable rule of exponents is ...
(a^b)/(a^c) = a^(b-c)
__
The diameter of Mars can be expressed several ways.
7000 = 7×1000 = 0.7×10,000 = 0.7×10⁴
