Answer:
2(x+y) - 23 or
2x + 2y - 23
Step-by-step explanation:
twice the sum of x and y means
2(x+y)
decreased means minus or -
decreased by 23 means
- 23
twice the sum of x and y decreased by 23
2(x+y) - 23
2(x+y) = 2x + 2y
2x + 2y - 23
Answer:
x = 2

Multiply them:
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.
