Answer:
The answer is 4 minutes
Step-by-step explanation:
I divided 825 by 3 and got 165. If you multiply 165 by all the factors, you get approximately 4 minutes. It's the closest. Try that one.
Answer:
Are there two you're asking for?
#2: x ≥ 9
#3: x > -2
Step-by-step explanation:
#2 Work:
x - 13 ≥ -4
Step 1: Add 13 to both sides
x - 13 + 13 ≥ -4 + 13
Add -4 and 13 to get 9.
x ≥ 9
#3 Work:
x/2 > -1
Multiply both sides by 2. Since 2 is positive, the inequality direction remains the same
x/2 * 2 > -1 * 2
x > -2

Answer:
103°
Step-by-step explanation:
The law of sines tells you ...
sin(C)/c = sin(A)/a
sin(C) = (c/a)sin(A)
C = arcsin(c/a·sin(A)) = arcsin(37/19·sin(30°)) ≈ 180° -76.8° ≈ 103°
Obtuse angle C is about 103°.
