In parallelogram HIJK, the measure of angle H is 45 degrees. 1.Find the measure of J and explain how you know
s2008m [1.1K]

Answer:

45°

Step-by-step explanation:

A parallelogram is a polygon with 4 sides and 4 angles (that is a quadrilateral).

For a parallelogram ABCD, Opposite sides and opposite angles are equal (i.e. BC = AD and ∠A = ∠C).

Consecutive angles are supplementary that is ∠A + ∠B = 180°.

The diagonals of a parallelogram bisect each other also separating the parallelogram into two congruent triangles.

In parallelogram HIJK, ∠H and ∠J are opposite angles. hence:

∠H = ∠J (opposite angles of a parallelogram are equal)

∠J = 45°

What is the equation of the time that passes through the poin3,2 ani<br> has an undefined slope?
sesenic [268]

Answer:

x=3

Step-by-step explanation:

An undefined slope means it is a vertical line, and every possible point at that line is at x = 3. y does not depend on x, and x cannot be anything other than 3, so the equation is just x=3
