Answer:
∠4 and ∠12
A is correct
Step-by-step explanation:
Parallel lines r and s are cut by two transversals, parallel lines t and u
r || s and t || u
We are four parallel line. Two parallel line cuts two another parallel line.
Angle 8 is form by intersection of s and t line.
Corresponding angle: When two parallel lines are crossed by transversal line, the angles at matching corners are called corresponding angles.
For angle 8, t || u with s is transveral line.
Thus, ∠8 = ∠12 (By definition of corresponding angle)
For angle 8, s || r with t is transveral line.
Thus, ∠8 = ∠4 (By definition of corresponding angle)
Hence, ∠4 and ∠12 are corresponding angle of ∠8
18% because 20+3=23 and 134-3=131 and so you divide 23/131 and you get 17.55 which rounds up to 18%
Answer:
16n
Step-by-step explanation:
5n+11n=16n because 5+11 =16 and you just multiply each number by n.
Answer:
16 presents
Step-by-step explanation:
Since you know that one present is 3 cm of tape, if he used a total of 48 cm, you can divide 48 into 3 to get 16 presents.
