The measure of the angle 2 is 133° and the measure of the angle 3 is 47°.

<h3>Classification Angles</h3>

They are a lot of classifications for angles like: complementary angles, supplementary angles, right angles, and others. See below:

complementary angles - two angles whose the sum is equal to 90°.
supplementary angles - two angles whose the sum is equal to 180°.
right angles - angles whose the measure is 90°.

From the figure, it is possible to see that:

- the angles 1 and 3 are supplementary angles

- the angles 2 and 3 are supplementary angles

Therefore, if angle1 is 133°, you have:

angle_1 + angle_3 = 180

133 + angle_3 = 180

angle_3=180-133

angle_3=47°

If angle3 is 47°, you have:

angle_3 + angle_2 = 180

47+ angle_2 = 180

angle_2=180-47

angle_2=133°

Reflect across the line x=-3

SOVA2 [1]

Answer:

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x).

In the accompanying diagram, parallelogram ABCD has

Taya2010 [7]

Answer:

The area of the paralellogram is 24 square units.

Step-by-step explanation:

Geometrically speaking, the area of the parallelogram has an equation equivalent to the area formula for a rectangle, that is:

$A = b\cdot h$ (1)

Where:

$A$ - Area.

$b$ - Base.

$h$ - Height.

The base and height of the parallelogram are, respectively:

Base

$b = 8-2$

$b = 6$

Height

$h = 5-1$

$h = 4$

Then, the area of the parallelogram is:

$A = (6)\cdot (4)$

$A = 24$

The area of the paralellogram is 24 square units.

Which correctly gives the expression using addition? –17.9 – 4.2

Shkiper50 [21]

c. –17.9+(–4.2)

The General rule for adding and subtracting numbers 
1. Two integers with the same signs
Once 2 integers has the same sign, then just add the numbers.
For example
1. 1+1 = 2 
2. 2 + 5 = 7 

2. Two integers with different signs
When 2 integers has different sign, then find the difference
For example
1. 1-1 =0
2. 2 – 5 = -3 

3. Two integers that vary in sign
When 2 integers vary in sign, then it will depend who which number carries the largest value
For example 
1. -3 + 2 = -1
2. 2 – 1 = 1
