Given an isosceles triangle with vertex angle 90°. you drop a line segment from the vertex to the opposite side, to intersect at the midpoint. the segment you drew has a length of 3cm. why & how is the length of one of the isosceles sides 3 square root of 2 and not 3?

Determine the domain and range of the given function. the domain is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}. the range is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}.
