Question

PLEASE PLEASE HELP

Answer 1

The length of AB is $\boxed{5.3{\text{ cm}}}.$

Further explanation:

An altitude is a line that is perpendicular to a side and passes through opposite vertex.

The point at which all the three perpendicular bisectors of a triangle intersect each is known as circumcenter.

The cicumcenter can lie inside or outside the triangle.

Given:

X is the circumcenter of the triangle ABC.

The length of side AX is 5.3 cm, length of CX is 5.3 cm, length of XN is 3.2 cm, length of BN is 4.2 cm and length of side BM is 2.3 cm.

Explanation:

X is the center of the circle that circumscribed to a triangle ABC because X is the circumcenter of triangle ABC.

Therefore, the side AX, BX and CX are the radii of the circle with center X.

The radii of the circle are equal. Therefore, the value of BX is 5.3 cm.

Hence, the length of AB is $\boxed{5.3{\text{ cm}}}.$

Answer 2

X is the circumcenter of triangle ABC means that X is the center of the circle circumscribed to triangle ABD, as shown in the figure.

This means that All XA, XB and XC are radii of the circle with center X. Since AX and CX are 5.3 cm, then so is XB.

Answer: XB=5.3 cm.
