Answer:
(45,60)
Step-by-step explanation:
in a parallelogram, opposite angles are equal measure
2x-10 = y + 20
angles that lie on the same line add up to 180, since alternate angles of parallel lines and a transversal are equivalent
2x + 10 + 2x - 10 = 180
solving the equation with only Xs
4x = 180
x = 180/4 = 45
plug x = 45 into x and y equation
90-10 = y+ 20
80 = y + 20
y = 80-20 = 60
Answer:
B.)
Step-by-step explanation:
Area=theta/360*pi r^2 for any theta r
Answer:
2x-10=14
2x=10+14
2x=24
x=24/2
x=12.
i guess it cant have infinite solutions.........
