Answer:
a = 76 b = 22 c = 58 d = 68
Step-by-step explanation:
A. 180 - 133 = 47
so you have two angles found, which is 57 and 47. Add them together and subtract from 180. You get 76
B. 68 + 90 = 158
You subtract the 158 from 180 and get 22
C. This took some guess work, but when you multiply 58 by 2 you get 116. When subtracted from 180 you get 64. If you add 58 + 58 + 64, you get 180, so this made sense
D. There's an actual rule in trig that explains this, but I forgot it. If you look at the top angle, the other side of the line added to the 68 is a right angle. So you subtract 68 from 90 and get 12. Because there is already the right angle in the triangle, you just need the other two angles to equal 90, and because of the 68 that we found in the other triangle, this made sense.
Sorry, not the best at explanations. Hope that helped
This graph shows the solution on a Cartesian plane.
Likely your graph is a solution on a number line. It will have an open circle at x=2, and an arrow pointing to the left from that point.
Answer:
16n=16n or n=1
Step-by-step explanation:
5n + 11n = 16n add like terms
16n = 16n divide both sides by 16
n = 1
Do 14 times n which give you 14n. and divide by 3.
Answer: (14n)/3
Answer:
B.
Step-by-step explanation:
Since we have a dotted line, our inequality must be either < or >, so A and D are out. We are left with B and C. Since our line is positive, our answer must be B and not C.
Alternatively, you can graph each equation and choose the best answer that matches the graph.
