Find angles 1, 2, and 3

angle 1 = 51°,  angle 2 = 39°,  angle 3 = 90°

Step-by-step explanation:

Arrows on lines are used to indicate that those lines are parallel.

As the opposite lines are parallel, this indicates that angles 39° and angle 2 are alternate, which means they are equal.  So angle 2 = 39°

As the opposite lines are parallel, and we are given one of the interior corner angles as a right angle (90°), this means that all corner angles of the rectangle are 90°.  Therefore, angle 1 = 90° - angle 2 = 90 - 39 = 51°

Angle 3 is opposite to the right angle.  As the lines are parallel, angle 3 = 90°

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
