Well when two angles are supplementary they equal 180.
So if angle A is 80 degrees then that would mean that angle B equals 100 degrees.
Hope This Helped :)
That's easy if there is 100 chairs there would be 10 rows with ten chairs in each row
Answer:
r = √( s/4π)
Step-by-step explanation:
s = 4πr²
s/4π = 4πr²/4π
r² = s/4π
√(r²) =+/-√( s/4π)
r = √( s/4π) Because r is a radius of the circle , it should be positive.
Answer:
The value of x is 9.
Step-by-step explanation:
55°
(3 x + 23)
75°
The sum of all the angles of triangle is 180°.
55 + 3 x + 23 + 75 = 180
3 x = 27
x = 9
So, the value of x is 9.
