(68 + 82 + 87 + 89 + x) / 5 > = 80
(326 + x) / 5 > = 80
326 + x > = 80 * 5
326 + x > = 400
x > = 400 - 326
x > = 74.......u would have to make at least a 74 to earn a B
Answer:
300!
Step-by-step explanation:
Because square feet is area and area is length (25) and width (12)
Answer/Step-by-step explanation:
✔️Find AC using Pythagorean Theorem:
AC² = 25.2² - 11.3²
AC² = 507.35
AC = √507.35
AC = 22.5 (nearest tenth)
✔️Find m<A using trigonometric ratio:
Reference angle = A
Opp = 11.3
Hyp = 25.2
Sin(A) = opp/hyp
Sin(A) = 11.3/25.2
A = sin^{-1}(11.3/25.2)
A = 26.6° (nearest tenth)
✔️Find m<B using trigonometric ratio:
Reference angle = B
Adj = 11.3
Hyp = 25.2
Cos(A) = adj/hyp
Cos(A) = 11.3/25.2
A = cos^{-1}(11.3/25.2)
A = 63.4° (nearest tenth)
