Answer:
Step-by-step explanation:
5. a) ∠1 and ∠2 are remote interior angles of ∠ACD so that means that ∠ACD = ∠1 + ∠2
b) Because an exterior angle is the sum of its two remote interior angles it makes sense that an exterior angle is greater in measure than either of its remote interior angles.
6. BD = DB Reflexive property
∠3 = ∠5, ∠4 = ∠6 Alt. int. angles
ΔADB = ΔCDB ASA
7. AB = BC Def. of midpoint
∠1 = ∠2 Given
∠BAE = ∠CBD Corresponding angles
ΔBAE = ΔCBD ASA
∠D = ∠E CPCTC
Answer:
D) 5/13
Step-by-step explanation:
Sin x = Opposite / Hypotenuse
Opposite side length = 5 cm
Hypotenuse length = 13 cm
Sin x = 5/13
The expression shown is an arithmetic expression. An arithmetic expression results in a numeric value.
The answer by the way is -6.
