We need to convert 135.28º in degree, minute, and second measure.
In order to do so, notice that:
Also,
Thus, we have the proportion:
<em>degrees minutes</em>
<em> 1 60</em>
<em> 0.28 x</em>
Then:
Thus:
Now, notice that:
Thus, we have the proportion:
<em>minutes seconds</em>
<em> 1 60</em>
<em> 0.8 y</em>
Then:
Therefore:
And the first option is correct.
Answer:
Step-by-step explanation:
The axes x and y are calibrated in 0.25
If the circle is carefully considered, the radius r of the circle is:
r = -1.25 - (-2)
r = 0.75 units
The equation of a circle is given by:
The center of the circle (a, b) = (-2, -2)
Substituting (a, b) = (-2, -2) and r = 0.75 into the given equation:
