Fittoniya [83]

Answer:

In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/x or x⁻¹, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a/b is b/a. For the multiplicative inverse of a real number, divide 1 by the number.

Step-by-step explanation:

To find the reciprocal, divide

HELP ASAP!!! THANK YOU!!!
alex41 [277]

Answer:

Additional information required is

<DBA = 90°

Step-by-step explanation:

<DBA + <DBC = 180° [Linear pair]

=> <DBA = 180° - <DBC

=> <DBA = 180 - 90

=> <DBA = 90

Hence, both the angles <DBA = <DBC = 90°

As we know that when a perpendicular bisector bisects a straight line both the angles should be,

180° ÷ 2 = 90°

And above conditions also prove that

<DBA = <DBC = 90°

<em><u>Hence, DE is a perpendicular bisector of AC </u></em>
