Answer:12
60×.20= 12
I hope this is good enough:
{y|1 > y}, (-∞, 1); you did not specifically mention what notation you needed, so I wrote both [Internal Notation and Set Notation].
Answer:
x = 7
recognize that this is a right triangle with one of the internal angles = 45°. This means that the other angle not shown is 180 - 90 - 45 = 45°
This makes the triangle an isosceles triangle.
If so, x must be the same length as the other side adjacent to 90°
i.e x = 7
Answer: The measure of the supplement of an angle of measure 0° is 180°
(45,60)
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
