Lets suppose his initial weight was 60 kilograms

A gain of 20%  would make his new eight  60 + 20*60/100

=  60 + 12

= 72 kg

he lost 25% of this:-

= 72 -   25 * 72/100 =  54 kg

This = (54/60) * 100  = 90% of his beginning weight  Answer

How would I do this? What would it be?
Vinvika [58]

50

Step-by-step explanation:

Since AE is the bisector of angle BAC,so angle BAE and Angle CAE is equal. Here Angle CAE and Angle EAC is same.

therefore,

m(Angle BAE)=m(Angle EAC)

x + 30 = 3x - 10

or, 2x=40

or, x=20

Hence,

m(Angle EAC)=

3x - 10

=

(3 \times 20) - 10  = 60 - 10 = 50
