Answer:
184.85 square mm
Step-by-step explanation:
The area of a sector of a circle is 
, where r is the radius and 
is the angle in radians subtended by the arc at the centre of the circle.
Since, diameter = 40.6 mm
So, radius(r)=20.3 mm and =
radians
So, area of sector=
=
=184.85 square mm
First put into slop intercept form
Y=mx+b. Y=1/3-1 then solve
Answer:
C
Step-by-step explanation:
The sum of the angles is 90
2x + x = 90
3x = 90
x = 30
the angle ABC is 2x, so it means that is the double of x, so it is 60 degrees
