Answer:

<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>9</u></em></h2>

Step-by-step explanation:

<h3><em><u>To</u></em><em><u> </u></em><em><u>Find</u></em><em><u>:</u></em><em><u>-</u></em></h3>
  • Value of x

<h3><em><u>Given</u></em><em><u>:</u></em><em><u>-</u></em></h3>
  • 46° and (5x - 1)° are complementary angles

<h3><em><u>Solution</u></em><em><u>:</u></em><em><u>-</u></em></h3>

As we know,

Complementary angles:

The angles whose sum results to 90° are known as the <em><u>complementary</u></em><em><u> </u></em><em><u>angles</u></em><em><u>.</u></em><em><u> </u></em>

So,

46° + (5x - 1)° = 90°

  • <em>[</em><em>Since</em><em> </em><em>complementary</em><em> </em><em>angles</em><em>]</em>

=> 46 + 5x - 1 = 90

  • <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

=> 45 + 5x = 90

  • <em>[</em><em>On</em><em> </em><em>subtracting</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>with</em><em> </em><em>45</em><em>]</em>

=> 45 + 5x - 45 = 90 - 45

  • <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

=> 5x = 45

  • <em>[</em><em>On</em><em> </em><em>dividing</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>with</em><em> </em><em>5</em><em>]</em>

=  >  \frac{5x}{5}  =  \frac{45}{5}

  • <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

=> x = 9

<em><u>Hence</u></em><em><u>,</u></em><em><u> </u></em><em><u>required</u></em><em><u> </u></em><em><u>value</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>9</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>

In a right triangle the length of a hypotenuse is c and the length of one leg is a, and the length of the other leg is b, what i
Inessa05 [86]

To solve this problem you must apply the proccedure shown below:

1. You need to apply the Pythagorean Theorem:

c^{2}=b^{2}+a^{2}

Where <em>c</em> is the hypotenuse and the legs are<em> a</em> and <em>b.</em>

2. Now, you must substitute the values given in the problem above and solve for <em>b</em>:

(2b)^{2}=b^{2}+12^{2}\\4b^{2}=b^{2}+144\\4b^{2}-b^{2}=144\\3b^{2}=144\\b=\sqrt{\frac{144}{3}}\\b=6.92

Therefore, the answer is: The value of <em>b</em> is 6.92

PLEASE HELP Find the area of the rectangle, to the nearest hundredth, with a base of 5 inches and a height = 2.5 inches. Type a
il63 [147K]

Answer:

The area of a rectangle with a width of 5 inches, and a height of 2.5 inches, would have an area 12.5 inches!

Step-by-step explanation:

To find the area of a rectangle, simply multiply the width (W) by the length (L) to find the area (A) of the rectangle.

A = W x L

A = 5 inches x 2.5 inches

A = 12.5 inches

Hope this helps! :)
