b. False

Answers

Answer 1

Answer:

Answer:

The given statement is false.

Step-by-step explanation:

A trapezoid has all three types of symmetry.

This is false.

An isosceles trapezoid is a trapezoid with congruent base angles. It has at least 1 and only 1 axis of reflectional symmetry.

A rectangle has 2 reflectional symmetries.

An isosceles trapezoid has no rotational symmetry.

Answer 2

Answer:

b. False

It does not have rotational, reflection, or point symmetry.

<1 is a complement of <2, and m<1=66. find <2

Answers

The measure of angle <2 is 24 degrees.

We know that, Complementary angles are when two angles add up to 90 degrees.

When two angles are complementary, their sum is 90 degrees.

Here, from this information we have to find the measure of angle <2.

Given that angle <1 is a complement of angle <2, we can set up the following equation:

m<1 + m<2 = 90

Substitute the given value for angle <1:

66 + m<2 = 90

Now, isolate m<2 by subtracting 66 from both sides of the equation:

m<2 = 90 - 66

m<2 = 24

So, the measure of angle <2 is 24 degrees.

Step-by-step explanation:

merchandise which is regularly $4.88 is on sale for 25% off. a customer buys 3 items. what is the total for 3 items?

Answers

If you would like to know the total price for 3 items, you can calculate this using the following steps:

25% of $4.88 = 25/100 * 4.88 = $1.22
$4.88 - $1.22 = $3.66

3 * $3.66 = $10.98

The correct result would be $10.98.
