Tanα=y/x
α=arctan(y/x), we are given the point (3.2, 6.2) so:
α=arctan(6.2/3.2)°
α=arctan(1.9375)°
α≈62.7° (to nearest tenth of a degree)
Answer:
287.94 (c)
Step-by-step explanation:
So first we calculate the cost of the game system after tax is added:
$299 × 1.07= $319.93
$319.93 IS THE PRICE OF THE GAME SYSTEM AFTER TAX IS ADDED.
Then we calculate the price after discount:
$319.93×0.90= $287.937
Even though the aswer isn't exact whe rounded off the answer is $287.94.
SO THE FINAL ANSWER IS $287.94.

The secant is the distance from the center to the vertical tangent in a certain direction.
Answer: perimeter = 96mm, Area = 564mm².
Step-by-step explanation:
From the diagram, it is a trapezium, it has a rectangle joined together by a right angled triangle. Now to find the perimeter, we add all the dimensions together. To get the other side of the rectangle, which is also the perpendicular height of the figure, we take the Pythagoras. Let the perpendicular height = x
Therefore,
25² = ײ + 7²
625 = x² + 49
x² = 625 - 49
x² = 576
x. = √576
= 24.
Now the perimeter
= 20 + 25 + 7 + 20 + 24
= 96mm.
Area of the figure will be
= 1/2( a + b )h
Where a = 20, b = 20 + 7 = 27 and h = 24, now substitute for the values
( 20 + 27) x 24
---------------------
2
= 47 x 24/2
= 47 x 12
= 564mm²
