Answer:
The third angle is 50°
Step-by-step explanation:
All three angles MUST equal to 180°
30 + 100 = 130
180 - 130 = 50
The third angle is 50°
Answer:
The next two numbers are -7500 and 37500
Step-by-step explanation:
To find the pattern, divide any number by the previous.
-300/60 = -5.
Meaning they are being multiplied by -5, so we can just multiply this to the last number.
1500 * -5 = -7500,
-7500 * -5 = 37500.

Answer:
The standard form of the ellipse is . Coordinates of the foci are and , respectively.
Step-by-step explanation:
The equation of a ellipse centered in the origin in standard form is defined by following formula:
(1)
Where are the coefficients of the ellipse.
Now we proceed to transform the equation of the ellipse in general form into standard form by algebraic means:
Since , then major axis of the ellipse is located in y-axis. The distance between center and focus () is calculated by following Pythagorean identity:
(2)
The location of the foci are represented by and . If we know that , then the location of the foci are, respectively:
,
