length of common tangent

The centers of two circles of radii 13.2 cm and 15.6 cm are 30 cm apart. Length of the common tangent is => 18.4 cm. or 8.4 cm. or 28.4 cm. or 13.4 cm...

Definition - The figure is a unit circle, with origin O as centre cuts the x-axis at A (1,0) and let a variable point moving on the circumference move through an arc length q . i.e., AP = p( q ). The coordinates at the position of p( q ) are p(x,y) = (cos q , sin q ). Then the tangen..

The tangent and cotangent came via a different route from the chord approach of the sine. These developed together and were not at first associated with angles. They became important for calculating heights from the length of the shadow that the object cast. The lengt..

Graph the equation x ² + ( y - 1)² = 9 . Then draw a line segment from (6, 0) as a tangent to the circle. Find the length of this tangent. => 4 2 units or 2 7 units or 2 3 units or 1 2 units..

Two circles of radius 31 cm each intersect each other. If their centers are 49.6 cm apart, then what is the length of the common chord? => 37.2 cm or 39.2 cm or 47.2 cm or 37.2 2 cm..

Tangents, drawn from points E and A are perpendicular to each other. Radius of circle with center O is a cm and tangent from A is b cm long. The length of the tangent from E, is [Given a = 2 and b = 3.] => 8 cm or 10 cm or 5 cm or 1 cm..
