Answer:
14.9 cm
Step-by-step explanation:
To find c using the Law of Sines, you must know angle C. That is found from ...
C = 180° -A -B = 180° -150° -12° = 18°
Then the law of sines tells you ...
c/sin(C) = b/sin(B)
c = b·sin(C)/sin(B) = (10 cm)·sin(18°)/sin(12°)
c ≈ 14.9 cm
Answer:
3 3/5
Step-by-step explanation:
it is right because equivalent fractions are different fractions that name the same number. i think this is right. i hope so. good luck
CF = FG = GC because it is equilateral triangle
So
3x + 0.8 = 2x + 3
3x–2x = 3 – 0.8
X = 2.2
Putting this value to DE
IT IS ALSO A EQUILATERAL TRIANGLE
SO
5x + 4 = 5× 2.2 +4 =
11+4 = 15
All side will be 15 of triangle CD = DC = CE = 15
