You didn’t post the question. If you post the questions, I can help.
Also, I think you can search the question and find the answers… I remember doing this one.
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:
Step-by-step explanation:
Total Cost = 150 + 69.50*12
Total Cost = 150 + 834
Total Cost = 984
Hidden in that is a 6% sales tax
Cost before sales tax = 1.06 * x = 984. This is the key step. The 6% sales tax is hidden in the 1.06. So you call the original price = x.
1.06 * x = 984 Divide by 1.06
x = 928.3 without the sales tax
The question seems to be answered by 984. The sales tax is in that cost.
Answer:
r = 21 cm
Step-by-step explanation:
The radius of a circle is 1/2 of the diameter
r = 1/2d
r = 1/2(42)
r = 21 cm
Answer:
y +1 = 4/3( x-9)
Step-by-step explanation:
Point slope form of an equation is
y-y1 = m(x-x1)
where m is the slope and (x1,y1) is a point on a line
y - -1 = 4/3( x-9)
y +1 = 4/3( x-9)
