Answer:
Step-by-step explanation:
It is given that A tangent-tangent angle intercepts two arcs that measure 135 degrees and 225 degrees, thus in this the vertex lies outside, therefore
The measure of the tangent tangent angle is the half of the difference of the two given arc, that is
⇒
⇒
Therefore, The measure of the tangent tangent angle is 45 degrees.
Answer: True.
Step-by-step explanation: The motive of all statistical tests is to check whether all the variables or unknown quantities we are using in the test are independent of each other or are related among themselves.
Also, when we write an article, we should always check whether the statistical test we are using is suitable for the type of data concerned or not.
Furthermore, if a statistical test come out to be invalid, then it may be possible that there are some questions that are misinterpreted.
Thus, the answer is true.
Answer:
Step-by-step explanation:
Diameter of a model of earth (D) = 25.6 cm
Radius of a model of earth (r) =
Earth has the shape of a sphere.
Total surface area of a sphere =
