Answer:
It would be Choice C, 12.4 feet.
Step-by-step explanation:
By using Pythagoras Theorem a² + b² = c²
c²- b²= a²
13²-4²=
169 - 16 = √153
√153 = 12.3693168769
12.3693168769 ≅ 12.4
Answer:
45000 + 2500x = 54000 + 1500x
Step-by-step explanation:
Jerry has a new job and earns a salary of $45,000 and she will receive a salary increment of $2500 per year.
Now, Victoria has a new job and earns a salary of $54,000 and she will receive a salary increment of $1500 per year.
If after x years their salary becomes the same, then
45000 + 2500x = 54000 + 1500x
⇒ 1000x = 9000
⇒ x = 9 years. (Answer)

Answer:
Step-by-step explanation:
Supplementary angles add up to 180°.
If the angle is x, its supplement is 180°-x.
x = (180°-x) - 78°
x = 51°
supplement = 180°-x = 129°
The angles are 51° and 129°
