Answer:
All to 1 decimal place
3) a = 11.4
4) b = 11.2
5) c = 4.5
6) e = 6.4
7) f = 30.8
8) g = 67.9
Step-by-step explanation:
Step-by-step explanation:
3) cos(18) = a/12
12xcos(18) = a
a = 11.4
4) tan(25) = b/24
b = 24xtan(25)
b = 11.2
5) cos(51) = c/7.2
c = 7.2xcos(51)
c = 4.5
6) sin(28) = e/13.6
e = 13.6 x sin(28)
e = 6.4
7) cos(47) = 21/f
f = 21/cos(47)
f = 30.8
8) sin(33) = 37/g
g = 37/sin(37)
g = 67.9
All to 1 decimal place
20.5 is his hourly pay rate
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.
If your asking what d equals, then it’s 10
They can’t be similar. Similar triangles have congruent corresponding angles, and two angles are given on each. Neither of those correspond to another on the opposite triangle. Basically, there’s no way to have three congruent angles, so they aren’t similar.
