Parallel lines m and n are cut by a transversal. At the intersection of line m with the transversal, the uppercase left angle is 105 degrees. At the intersection of line n with the transversal, the bottom right angle is (3 x minus 15) degrees.
What is the value of x for which m || n?

x = 40
x = 5
x = 105
x = 30

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
