Anne wants to fill 12 hanging baskets with compost. Each hanging basket is a hemisphere of diameter 40 cm. Anne has 4 bags of compost. There are 50 litres of compost In each bag. Has Anne got enough compost to fill the 12 hanging baskets?

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.
