A train starts its journey at 11 o'clock towards east with velocity 45 km/h, while another train begins its journey at 12 o'clock from the same point towards south with velocity 6 km/h. Then the rate of increasing distance between the two trains at 3 o'clock afternoon = Km/h

Which shows the image of rectangle abcd after the rotation (x, y) → (–y, x)?

The radius of the circle is 4 cm and the measure of the central angle is 90° the area of the sector with a central angle measuring 90° and radius of length 4 cm is vt cm the triangle in the sector is 4 cm the area of the triangle is v/cm² the area of the segment of the circle is (471 - ) cm?

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles
