If you were to calculate the EXACT number, the cosine of theta would be rad.15 over 4.
Sine is opposite over hypotenuse, so the opposite would be 1 and the hypotenuse would be 4. Using the Pythagorean Theorem, you will see that the last side to your triangle is the square root of 15 (AKA rad.15). Cosine is adjacent over hypotenuse, thus rad.15 over 4.

32,000 and 42,000. I know this because the question states "Two Thousands." 32,000 and 42,000 are both two thousands because 32 and 42 both end with 2's because of the "Two" in "Two Thousand."

Use the diagram and given information to answer the questions and prove the statement.
Greeley [361]

Answer:

See explanation

Step-by-step explanation:

<u> ASA Postulate (Angle-Side-Angle):</u>

If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.

Consider triangles XYB and ZYA. In these triangles

  • ∠X≅∠Z (given)
  • XY≅ZY (given)
  • ∠Y is common angle

By ASA Postulate, triangles XYB and ZYA are congruent. Congruent triangles have congruent corresponding sides, so

F (x) = -3x + 2x – 5 Whatisf (-1)?​
eduard

Answer:

f(-1) = -4

Step-by-step explanation:

f(-1) simply means that what is f(x) when x = -1?

Just plug in -1 for <em>x</em> to find your answer:

f(-1) = -3(-1) + 2(-1) - 5

f(-1) = 3 - 2 - 5

f(-1) = 1 - 5

f(-1) = -4
