if the ellipse has a major axis of 12 inches, that means its major radius is half that, or 6, and if its minor axis is 7, then its minor radius is half that, 3.5.
12% as a fraction or mixed number in simplest form

Answer:
Find the value of x in each of the given figures.
Step by step explanation :
a. .. Let the triangle be ABC
we have to find the value of A
so
ATTQ ( According to the question) we have ::
B = 25°
C = 105° + ___ = 180° ( adjacent angles)
C = 75 ° = 180° - 105° ( transfer 105° from LHS to RHS)
The sum of all interior angles of a triangle is 180° .
so, A+B+C = 180°
A+ 25° + 75° = 180°
A+ 100° = 180°
A= 180° - 100°
A = 80°
therefore answer is 80°
b. .. Let the triangle be ABC.
we have to find the value of x
ATTQ , we have
A= 3x+2°
B=2x°
C = 152° + ___ = 180°
C= 180°- 152° = 28°
The sum of all interior angles of triangle is 180°
so, A+B+C = 180°
3x+2° + 2x° + 28° = 180°
first add the variables then numbers
5x° + 30° = 180°
5x° = 180° - 30°
5x ° = 150°
x° = 150° / 5
x = 30°
therefore answer is 30°
