This forms a right triangle with hypotenuse of length 15 and vertical component of length 4. Use the inverse of sine (vertical/hypotenuse) to get arcsin(4/15) = 15.4 degrees which rounds to 15
Final answer:
Answer choice B, 15 degrees
3. A.-2
4. B.2
Hope this helps
3.5ft(12in/ft)=42 inches
So all dimensions must be LESS than 42 inches...
Only choice C. satisfies this condition...
Step-by-step explanation:
Coordinates of Point R = (0, y).
We have PR = QR.
=> (-2 - 0)² + (6 - y)² = (9 - 0)² + (3 - y)².
=> 4 + (6 - y)² = 81 + (3 - y)²
=> y² - 12y + 40 = y² - 6y + 90
=> 6y + 50 = 0
=> y = -25/3.
Hence the answer is (0, -25/3).
Coordinates of Point S = (x, 0).
We have PS = QS.
=> (-2 - x)² + (6 - 0)² = (9 - x)² + (3 - 0)²
=> (-2 - x)² + 36 = (9 - x)² + 9
=> x² + 4x + 40 = x² - 18x + 90
=> 22x = 50
=> x = 25/11.
Hence the answer is (25/11, 0).
