Answer:

Step-by-step explanation:

if you multiply everything by 5, then you can get rid of the fraction and the equation would now look like this:

x - 40 = 20

and now you can answer this simply

x - 40 = 20

+40 +40

x = 60

and since you multiplied 5 beforehand, now you have to divide by 5 to get the real answer

60 ÷ 5 = 12

therefore, x = 12

Given that the triangles shown below are similar, what is the value of x?

Montano1993 [528]

Using proportions, it is found that the value of x is of x = 5, hence option A is correct.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

Since the triangles are similar, the lengths are proportional. Researching the problem on the internet, we have that the proportions are given as follows:

A side with a length of x is proportional to a side with length 25.

A side with a length of 3 is proportional to a side with length 15.

Hence:

$\frac{x}{25} = \frac{5}{25}$

Simplifying the denominators:

x = 5.

Please help if you can <3

Bogdan [553]

Answer:

1) x = 71

2) x = 117

m<1: 35

m<2: 77

m<3: 52

m<4: 77

m<5: 65

m<6: 25

Step-by-step explanation:

x + 41 + 68 = 180

x + 109 = 180

x = 71

x + 47 + 16 = 180

x + 63 = 180

x = 117

<2 + 103 = 180

<2 = 77

<1 + 68 + 77 = 180

<1 + 145 = 180

<1 = 35

<4 + 103 = 180

<4 = 77

<5 + 41 + 77 = 180

<5 + 115 = 180

<5 = 65

<6 + 65 = 90

<6 = 25

<3 + 103 + 25 = 180

<3 + 128 = 180

<3 = 52
