180 - ( 19x + 3 ) + 9x + 1 + 11x - 2 = 180
180 - 19x - 3 + 9x + 1 + 11x - 2 = 180
- 19x - 3 + 9x + 1 + 11x - 2 = 180 - 180
- 19x - 3 + 9x + 1 + 11x - 2 = 0
x - 4 = 0
x = 4
Answer:
C. x=22°
Step-by-step explanation:
Since the principles of sine and cosine are based upon right triangles, the two angles have to be complementary, adding up to 90. Thereby, in your equation, (x+2) + (3x) = 90. Combining like terms gives you:
4x + 2 = 90 subtract 2 from both sides
<u>- 2 -2</u>
<u>4x = 88</u> divide both sides by 4
4 4
x = 22
Answer:
see below
Step-by-step explanation:
Only the first of your graphs has the points in the right places.
The x-value is the horizontal coordinate; the y-value is the vertical coordinate. So the point (x, y) = (-5, 2) is 5 units left of the y-axis and 2 units up from the x-axis. Only one graph has that point properly plotted.
