Answer:
27°
Step-by-step explanation:
Since BD is a diameter then arc BD = 180°
∠ APE = 180° - (90 + 63)° = 180° - 153° = 27°
The measure of the arc AE is equal to the angle at the centre subtended by it.
arc AE = ∠ APE = 27°
Yes, because there are two pairs of congruent corresponding angles
Answer:
11/48
Step-by-step explanation: You use KCF.
1. Keep 11/12
2. Change division to multiplication
3. Flip 4/1 to 1/4
4. Multiply 11/12 and 1/4
5. You get your answer 11/48
The a and b determine how big or small the shape of the conic section is.
<span>For the different conic sections given through the equations </span>
<span>Circle: x^2/a^2 + y^2/a^2=1 </span>
<span>Ellipse: x^2/b^2+y^2/a^2 = 1 </span>
<span>Hyperbola: x^2/a^2 - y^2/b^2 = 1 </span>
<span>When trying to isolate cos and sin from those equations to get cos^2t + sin^2 t = 1 you can determine the conic section when substituting cos t = x/a and sint = y/b into cos^2t+sin^2t square it and then refer to the conic section equations to determine the conic section. x defines the major axis and y is the minor axis. a and b provide the coordinate pairs</span>
Answer:


when
and 
so the tangent slopes are
and -2 at those x.
The lines are y = 2x + b and y = -2x + c.
We need to find b and c.
The first line must go through (-8,0) and the second one through (-10,0).
For the first line: 0 = 2*(-8) + b and b = 16.
For the second line: 0 = -2*(-10) + c and c = -20.
