Answer:
5
Step-by-step explanation:
Use pythagorean theorem. The rise is 3 units and the run is 4 unites. Now the length of the line we are trying to find is a hypothenuse(the side opposite of the right angle
Answer:
when P(x,y) is reflected in y=x line then
P(x,y) = P(y,x)
A(2, -1)= A(-1, 2)
B(-2, -1) = B(-1, -2)
C(2, 1)= C(1, 2)
D(1,2)= D(2,1)
Step-by-step explanation:
C. reflex, because all of the others are triangles
The arc is defined by an angle of 1.05 radians, and a length of 1.05 units.
<h3 /><h3>How to get the angle in radians?</h3>
Remember the relation:
180° = 3.14 radians.
Then:
60° = (60°/180°)*3.14 rad = 1.05 rad.
Now, for a circle of radius R, an arc defined by an angle θ has a length:
L = θ*R
Then the length of this arc is:
L = 1.05*1 unit = 1.05 units.
