Answer:
3,4,5 are congruent angles
Step-by-step explanation:
Congruent Angles have the same angle (in degrees or radians). That is all. They don't have to point in the same direction. They don't have to be on similar sized lines.
Answer:
W = 11/2, L = 14 sq ft
Step-by-step explanation:
Area = 77ft
L = length, W = width
L = 3 + 2W
L * W = 77
Plug W in to find the L
Let the measure of the unknown angle is x °
Supplementary angles sum up to 180°. So the supplementary angle of x° will be (180 - x)°
According to the given data, measure of x is 40° less than 3 times the measure of its supplementary angle (180 - x). So we can set up the equation for this scenario as:

So the degree measure of the required angle is 125°.
<h2>
Radius of a Circle Given Center and Point</h2>
To find the radius of a circle when we're given the coordinates of its center and a point it contains, we can use the following formula for distance:

is one point and
is another
<h2>Solving the Question</h2>
We're given:
- Center: (-2,1)
- Point: (2,-1)
Plug these given points into the formula for distance:

<h2>Answer</h2>
Therefore, the radius of the circle is
units, or approximately 4.47 units.
