Answer:
angle 1
Step-by-step explanation:
Using the trigonometric mnemonic SOH CAH TOA, we know that cos or cosine is the ratio between the adjacent side and hypotenuse side.
This means that if cos A = 0.48, A is the measure of the angle which it's relative adjacent side divided by the hypotenuse of the triangle will be around 0.48.
Let's try angle 2, cos (angle 2) = adjacent / hypotenuse = 7.8 / 8.9 = 0.876404494382 ≈ 0.87 ≠ 0.48. Since the proportions are not equal, this angle cannot be the one marked as A.
Since angle 3 is a right angle, the adjacent could be either side so it cannot be correct. Thus angle 1 is correct.
1.If AC = 5x + 2 and BD = 2x + 20, find BD. 5x+2=2x+20 D BD=216)+20=32 ... 5. In the accompanying diagram, ABCD is a rectangle. E is a point on CD:
Total # multiplied by % =portion
=2000 * 85%
=2000 * 0.85
=1,700 # of albums autographed
Hope this helps! :)
Answer:
for A plug in those numbers on the right and on the left start with 1 and move up(for example 1,2,3,4,5...)
