The measure of ∠ABD is (0.18x+54)° and the measure of ∠CBD is (0.07x+39)°. find the value of x.
snow_lady [41]

Answer:

x = 348

Step-by-step explanation:

From the given we can tell it a supplementary angle.

<u>Don't know what supplementary angle is?</u>

<em>Supplementary angle are angles that :</em>

<em>Equal 180 °</em>

<em />

<u><em>Solve:  </em></u>

<em>Since,</em>

<em>∠ABD is (0.18x+54)° </em>

<em>∠CBD is (0.07x+39)°</em>

<em />

<em>Thus,</em>

<em>(0.18x+54) + 0.07x + 39 = 180</em>

<em>Group likes terms:</em>

<em>0.25x + 54 + 39 = 180</em>

<em>0.25 + 93 = 180</em>

<em>Subtract 93 from both sides</em>

<em>0.25x = 87</em>

<em>x = 348</em>

<em />

<em>Check Answer:</em>

<em>0.18(348) + 54 + 0.07(348) + 39 </em>

<em>= 180</em>

<em />

How do you think Pythagoras' broad interests, life experience, and beliefs influenced his work?
Leviafan [203]
The arts the Greeks searched some reality behind the appearances of things. The early Archaic sculpture represents life in simple forms, and it seems that it was influenced by the earliest Greek natural philosophies. There was a general Greek belief that nature expresses itself in ideal forms, and it was represented by a type which was mathematically calculated. This can be observed in the construction of the first temples. The original forms were considered divine, and the forms of the later marble or stone elements indicate that there was an original wooden prototype. When the dimensions changed, the architects searched in mathematics some permanent principles behind the appearances of things <span>these ideas influenced the theory of Pythagoras and his students who asserted that "all things are numbers.</span>
