Question

PLEASE HELP ASAP and explain

Answer 1

XC = 20

Explanation:

We see that AD is congruent to DC and also, XD is common to both triangles ADX and CDX, so, from the leg-leg theorem,

The triangles ADX and CDX and congruent.

Hence the hypotenuses must be equal.

Hence, AX = XC

or,

2m + 10 = 4m

10 = 4m - 2m

10 = 2m

m = 10/2

m = 5

Then, XC = 4(m)

so,

XC = 4(5)

XC = 20
