In this problem, how would I find the value of Z ?

z = 30

Step-by-step explanation:

WX and VU are congruent

2z + 10 = z + 45

subtract z from both sides (z + 10 = 45)

subtract 10 from both sides (z = 30)

the answer is z = 30

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
