Answer:
900
Step-by-step explanation:
perimeter: P = 2w + 2h
P = 2(20) + 2(25)
P = 40 + 50
P = 90
Multiply perimeter by 10:
90 × 10 = 900
3x3 -4= 5 5(-1)= -5 -5(-4)= 20
Add -46 and -46 to the final answer
The positive measure is 220° and the negative measure is -140°.
<h3>How to find the measures of the angle?</h3>
First, we know that the reference angle is 40°, and it lies on the third quadrant.
So these 40° are measured from the negative x-axis (the axis where the quadrant starts).
This means that the angle measured in the standard way (from the positive x-axis) measures:
M = 40° + 90° + 90° = 220°.
To find the negative measure, we remember that any angle A is equivalent to:
B = A + n*360°.
Where n is an integer.
If we take n = -1 for our angle, we get:
M' = 220° + (-1)*360° = -140°.
So the positive measure is 220° and the negative measure is -140°.
