9.8 is the middle number which is the median
Use Law of Cosines g^2 = f^2 + h^2 -2fhCosG f^2 = g^2 + h^2 -2ghCosF h^2 = f^2 + g^2 -2fgCosH
f^2 = 28^2 + 15^2 -2*28*15Cos87 28^2 = 31^2 + 15^2 -2*31*15CosG
f^2 = 784 + 225 - 43.96 784 = 961+225 - 930CosG
f^2 = 965.0378 784 - 1186 = -930CosG
f = 31 -402 = -930CosG Divide by -930
.432258 = CosG
Cos^-1(.432258) = G
G = 64 degrees
Angle H = 180 - 64 - 87 = 29 degrees
Side f = 31 Angle F = 87 degrees
Side g = 28 Angle G = 64 degrees
Side h = 15 Angle H =29 degrees
Answer:13.5
Step-by-step explanation: 6:9
9:?
divide both by 3 2:3
now multiple 4.5. 9:13.5
Answer: -52
Step-by-step explanation: I just know
Answer:
4.) 7 : 4 = 36[g] : x [g]
7 * x [g] = 4 * 36 [g]
7 * x [g] = 144 [g]
x [g] = 144 [g] / 7
x [g] ≈ 20, 57 [g]
5.) 3:2 250
3x + 2x =250
5x=250
x=50
3x=3*50=150
2x=2*50=100
