Answer:
10. Not enough information
11. B ≈ 12.0°
12. A ≈ 34.1°
Step-by-step explanation:
10. Not enough information
11.
We need to use the Law of Sines, which states that for a triangle with lengths a, b, and c and angles A, B, and C:
Here, we can say that AB = c = 38, C = 128, and AC = b = 10. Plug these in to find B:
Solve for B:
B ≈ 12.0°
12.
Use the Law of Sines as above.
Solve for A:
A ≈ 34.1°

Answer:
84 ft^2.
Step-by-step explanation:
Use Pythagoras to find the value of h:
25^2 = h^2 + 7^2
h^2 = (25-7)(25+7)
h^2 = 576
h = √576 = 24
Area = 1/2 * 7 * 24
= 84.
Answer:
44
Step-by-step explanation:
The absolute value symbols turn any negative inside of them to a positive, so your expression is ...
2 + 4·3 +5·7 +1 -6
= 2 +12 +35 +1 -6
= 44
Answer:
66 I am pretty sure
Step-by-step explanation:
6 x 2 divided by 2 = 6
6 + 6 = 12 x 10 divided by 2 = 60
add them together
60 + 6 = 66
