Answer:
x = 21

Explanation:
In a parallelogram, each two opposite angles are equal.

In the given parallelogram ABCD, we can note that angles A and C are opposite angles. This means that they have equal measures.

Therefore:
∠A = ∠C
x + 17 = 2x - 4
17 + 4 = 2x - x
x = 21

We can check:
angle A = 21 + 17 = 38°
angle C = 2(21) - 4 = 38°
They are equal

Hope this helps :)

With similar triangles, the ratios of all three pairs of corresponding sides are equal
Elza [17]
<h3>Yes, this is true.</h3>

To be considered similar triangles, the angles must be the exact same, and the sides must be proportional. The side lengths do not have to be exactly the same, but they must be proportional (like a ratio, suppose one triangle has a side length of 1, and the similar triangle has a side length of 3. The ratio is 1:3, and all sides will follow this ratio.)

A dime has a diameter of about 18 millimeters. About how many millimeters long would a row of 34 dimes be?
Oliga [24]

It's hard to line them up exactly straight, with all of their centers
in a straight line.  It's much easier if you line them up on the floor
against a wall.

If you had 34 in a perfectly straight line, then the row would be

       (34) times (18 millimeters) =  612 millimeters long .
