Answer:
x = 133°
Step-by-step explanation:
Straight-line pair - A pair of angles that lie on a straight line.
<em>*</em><u><em>Property</em><em>*</em></u>
The sum of two angles of a straight-line pair is equal to <u>180°</u>.
The given angles – x and y – form a <u>straight-line pair.</u>
==> x + y = 180
<em>{</em><em>y</em><em> </em><em>=</em><em> </em><em>4</em><em>7</em><em>°</em><em> </em><em>(</em><em>given</em><em> </em><em>in</em><em> </em><em>t</em><em>he</em><em> </em><em>question</em><em>)</em><em>}</em>
<em>Substituting</em><em> </em><em>4</em><em>7</em><em> </em><em>for</em><em> </em><em>y</em><em>:</em>
==> x + 47 = 180
<em>Subtracting</em><em> </em><em>4</em><em>7</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>
==> x = 47 - 47 = 180 - 47
==><u> x = 133</u>
False. This is because no matter what the number is, the properties of multiplication and division stay the same. So, if one odd and even number multiply/divide, then the answer will be negative. But, if two numbers of the same sign (both either negative or positive) are divided/multiplied, they will both be positive. Therefore, the result is not always the same sign as the starting integers
Hope this helped! :D
Alright, the answer is B and I’ll tell you why. Look at the problem and see the order that they write the triangles in. ABC and XYZ, this is telling us that the angles in order are congruent to each other. Hope this helps :)
Answer: $20
Why: First add 3 to 4.25 to get 7.25, then you double it getting 15. You then times 15 by 1/3 to get 5 and then you times 5 by 4 to get your answer of $20.
