For which pair of functions is (gºf)(a) =lal-2?

yes.. it's proven to be 36.

the answer to this in exact form is 4/35 but in decimal form its 0.1142857

hope this if needed hmu

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.

simple 80 pieces in 1 sercing so 80*47=3760+20=3780
