Answer:
x = 6
Step-by-step explanation:
Since <F = <F, this shows that the triangles are similar. Therefore:
XZ/DF = XY/DE
12/8 = 9/X
Cross multiply
12X = 9*8
12X = 72
X = 72/12
X = 6
Hence the value of x is 6
My vote would be b. because generally when we are figuring area of a room, we are working with materials that are not exact and we usually round off .75 to the next foot. (I have experience in flooring!)
I am sure there are situations where you would want it to be exact however, such as using VERY expensive materials to cover.
First one.
tan(pi/2) is the asymptote, and 2pi/4*x = pi/2*x, between 0<x<2, goes from 0 to pi, so it only passes thru pi/2.

Answer:
7.970km
Step-by-step explanation:2km 30m=2000m+30m=2030m (1km=1000m)
total distance is 10km which is 10000m.
10000m Minus 2030m equals 7970m so this give's us the answer of 7.97km (7.970km) Hope this helps!
