Question

Brian weighed 135 kg. He lost 15kg in the first

week at the weight loss camp. He lost another 5kg the

2nd week. What percentage of his weight did he lose

in these 2 weeks?​

Answer 1

why is there an angle equation?

but to answer the first question....

Brian weighed= 135 KG

He lost= 15 KG

so 135-15=120

He lost= 5KG

120-5= 115

percentage= 115/100

=1.15%
