You can find the complementary angle for 28° first, which is 90°-28°=62°. Since this is a right triangle, you can then use trigonometry to find x (the hypotenuse). You have the angle and the adjacent side, so plug and play:
cos 62° = 350 / x
x = 350 / cos 62°
x = 745.5 ft
ANSWER
a=9
EXPLANATION
The given quadratic equation is

If x=1 is a solution, then it must satisfy this equation:



Therefore the value of 'a' is 9
Answer:
120 pounds I think
Step-by-step explanation:
Answer: b = 2a/h
Step-by-step explanation:
a = bh/2
multiply each side by 2
2a = bh
divide each side by h
2a/h = b
Answer:
Option b is the right answer.
