Answer:
x = 9
Step-by-step explanation:
5x + 27 = 45 + 3x
Subtract 3x from both sides
2x + 27 = 45
Subtract 27 from both sides
2x = 18
Divie both sides by 2
x = 9
Answer:
Option 3: transitive property
Step-by-step explanation:
The previous statements are
2. ∠2 ≅ ∠3 ⇒ 2. ver. ∠s theorem
And
5. m∠3 = m∠7 ⇒ 5. def. of congruent
So, The previous proved statement to make use of the transitive property reason or proof
∴ 6. m∠2 = m∠7 ⇒ 6. transitive property
Note: the transitive property states that: If a = b and b = c, then a = c.
11/18 or about 61% probability.
