Answer:
I attached a pic
Step-by-step explanation:
Hope it helps you!!!
A = c/sin C, and b by the proportion b/sin B = c/sin C.
a/sin 37° = 4380/sin 109°
a sin 109° = 4380 sin 37°
a = 4380 sin 37°/sin 109° ≈ 2787.8
b/sin 34° = 4380/sin 109°
b sin 109° = 4380 sin 34°
b = 4380 sin 34°/sin 109° ≈ 2590.4

let assume # denotes angle signs
now
as sum of 3 angels in triangle is 180
#2 +#3 +#4 = 180
also
#1 + #4 = 180
so equating both equation
#2 +#3 + #4 = #1 + #4
#4 will be cancelled from both side then
#2 + #3 = #1
proved
14)
ratio is 1:3:5
so Alma adsed it wrong. it should be 9x in 2nd line.
correction
x + 3x + 5x = 180
9x = 180
x = 180/9 = 20
so 1st angle = x = 20
2nd angle = 3x = 3×20=60
3rd angel = 5x = 5×20 = 100
4(x – 3) + 4 < 10 + 6x
Distribute the 4 on the left side.
4x -12 +4 < 10 + 6x
Combine like terms on the left side.
4x-8<10 +6x
Subtract the 6x from both sides.
-2x -8<10
Add the 8.
-2x <18
Divide by -2 & flip the inequality symbol (it's a math rule which states that if you multiply or divide by a negative, you must flip the inequality symbol).
x> -9
That's your final answer.
