The <em><u>correct answers</u></em> are:
A, C and D.
Explanation:
The height of a parallelogram must be perpendicular to, or make a right angle with, the base of the parallelogram.
In parallelogram A, it is a rectangle; this means by definition the side is at a right angle with the base and is therefore a height.
In parallelogram B, the short side is marked as the height. However, this side is not at a right angle with the base, so it cannot be a height.
In parallelogram C, the height is drawn perpendicular from the vertex of the top base to the (extended) bottom base; this is correct, since it is at a right angle.
The same is true of parallelogram D.
Well it depends on what the model is but if it's an IRA or whatever so if you make your own model that's easy
Answer:
r = 7
Step-by-step explanation:
The common ratio r of a geometric sequence is
r = 
= 
, that is
r = 
= 
= 7
Answer:
Angle S has a measure of 50°
Step-by-step explanation:
When comparing the angles of a triangle, they are written with the matching angles in the same order. (sorry for bad explanation here)
You have ∆ QRS as congruent to ∆ XYZ. This means angle Q is congruent to angle X, angle R is congruent to angle Y, and angle S is congruent to angle Z. <u>As you can see in ∆ XYZ, angle Z is 50°. Therefore, angle S and angle Z are both 50°</u> (but only angle S is an option)
