Question 6: if a1 1 verify that, (a) 5a 3a+2a (b) (at)t

step-by-step explanation:

#12 the answer is the third option

triangle eg 7.5 × cos "a" or 7.5 × sin "b" or 6 tan"a"

the transitive property of equality.

step-by-step explanation:

the correct answer is:

the transitive property of equality.

explanation:

we know that  ∠bcd is congruent to  ∠pbc. we also know that  ∠pbc is congruent to  ∠bad.

we can substitute  ∠bad for  ∠pbc in the first angle congruence statement to give us:

∠bcd is congruent to  ∠bad.

algebraically, the transitive property states if a=b and b=c, then a=c. it basically allows us to substitute equal values. since that is what we did, this is the transitive property.
