Step-by-step explanation:
The vertices and foci are on the x-axis. Thus, the equation for the hyperbola will have the form x2a2−y2b2=1 x 2 a 2 − y 2 b 2 = 1 . The vertices are (±6,0) ( ± 6 , 0 ) , so a=6 a = 6 and a2=36 a 2 = 36 . The foci are (±2√10,0) ( ± 2 10 , 0 ) , so c=2√10 c = 2 10 and c2=40 c 2 = 40 .
100°
40°
60°
50°
Answer:
40
Step-by-step explanation:
AFE=120 so arc AE is also 120
those 3 angles add up to 180 and 180-120-20=40
The measure of ∠C is 40°.
When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
Angle measure of central angle is equals to measure of intercepted arc.
External angle formed outside a circle,
= Half the difference of the major and minor arc =
Angle measure of AFE
= arc AE = 120°
Thus:
m∠C = 1/2(120 - 40)
m∠C = 40°
So, the angle measure of C is 40°
Therefore, 40° is the measure of ∠C.
