A 7. A quadrilateral formed by joining the mid-points of the sides of a quadrilateral is a parallelogram. Prove it. Please explain with fig how it would be.

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?

Factor and solve to find roots x squared -x - 90 =0

Solve for x and select the correct answer
