Answer:
Area is 20
Perimeter is 24
A= L × W
Step-by-step explanation:
Area is found by multiplying the length by the width, which in this case is 10 × 2 = 20
Perimeter is found by adding all of the sides together, so 2 + 2 + 10 + 10 = 24
A= Legnth × Width or vise versa
Since you want to cancel something out, the book makes the 24 3 times eight so that both of the threes can be canceled out
Answer:
D. a line and a point not on that line
Step-by-step explanation:
That is how you determine a plane.
Answer:
in degrees: theta = 63.43°
in radians: theta = 1.11 rad
Step-by-step explanation:
To find the value of the angle theta that gives us tan(theta) = 2, we should use the inverse function of the tangent in the calculator, that is, the arc tangent function.
Then, if we use the arc tangent function (in some calculators, it may be shown as 'atan' or 'tan^-1') in the value 2, we would find:
atan(2) = 63.435°
So the angle theta that gives us tan(theta) = 2 is theta = 63.43°.
Be sure to check in the calculator if the answer is given in degrees or radians.
In radians, we would find theta = 1.1071 rad (rounded to nearest hundredth: theta = 1.11 rad)
