Find the measure of the angle indicated in bold, which is 20x+5

Vikki [24]

24x-1+20x+5=180
44x+4=180
44x=176
x=4

Therefore, 20x+ 5 is equivalent to 20(4)+5
20(4)+5
80+5
85

Hope this helps :)

. How can you know if 2 shapes are congruent? Draw an example of 2 congruent triangles and label how you know.

ValentinkaMS [17]

Triangle ABC and triangle DEF are congruent by the SAS Congruence Postulate

<h3>What are congruent triangles?</h3>

Two triangles are said to be congruent if they have the same shape and their corresponding sides are also congruent.

We can say that two triangles are congruent using these 5 rules:

1: SSS or the side, side, side rule, that means that we have two triangles with all three sides equal.

2. SAS or side, angle, side states that in the two triangles, two sides and the included angle are equal.

3. ASA or angle, side, angle states that in two triangles, the two angles and the included side are equal.

4. AAS or angle, angle, side states that we have two triangles where two angles and the non-included side are equal.

5. HL or the Hypotenuse Leg rule states that, if the hypotenuse and one leg of one right-angled triangle are equal to the corresponding hypotenuse and leg of another right-angled triangle, then the two triangles are congruent.

Two triangles are said to be congruent if they have the same shape and their corresponding sides are also congruent.

Example:-From the diagram, given that:

AB = DE, BC = EF and ∠B = ∠E

Triangle ABC and triangle DEF are congruent by the SAS Congruence Postulate

Change<br>2.215(1 and 5 are recurring/repeating decimals)<br>in form of a/b

Romashka-Z-Leto [24]

Answer:

Answer:

2.215=2 43/200

Step-by-step explanation:

Showing the work

Rewrite the decimal number as a fraction with 1 in the denominator

2.215=2.215/1

Multiply to remove 3 decimal places. Here, you multiply top and bottom by 103 = 1000

2.215/1×1000/1000=2215/1000

Find the Greatest Common Factor (GCF) of 2215 and 1000, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 5,

2215÷5/1000÷5=443/200

Simplify the improper fraction,

=2 43/200

In conclusion,

2.215=2 43/200

1. is he equation true , false, or open

RideAnS [48]

Question 1:

For this case we have the following equation:

$5x ^ 2 = 6x + 11$

We observe that the equation is a polynomial of the second degree.

Therefore, the equation has two possible solutions.

The variable of the equation for this case is x.

In this case, we have an open equation because we have a variable.

Rewriting the equation we have:

$5x ^ 2 - 6x - 11 = 0$

Answer:

open, there is a variable.

Question 2:

For this case we have the following equation:

$2-8x = -6$

From here, we must clear the value of x.

For this, we follow the following steps:

1) Pass the value of 8x adding:

$2 = -6 + 8x$

2) Pass the value of 6 adding:

$2 + 6 = 8x$

3) Add the values on the same side of equality:

$8x = 8$

4) Pass the 8 to divide:

$x = \frac{8}{8} = 1$

Answer:

The value of x is given by:

$x = 1$

Question 3:

For this case we have the following equation:

$y = x-4$

The ordered pair solution is the one that satisfies both sides of the equation.

For the point (6, 2) we have:

$x = 6 y = 2$

Substituting values we have:

$2 = 6-4 2 = 2$

We observe that both sides of the equation are equal.

Therefore, the ordered pair solution is (6, 2)

Answer:

An ordered pair that is a solution of the equation y = x-4 is:

(6, 2)
