Answer:

Sum- 17 Difference- 7.6

Papessa [141]3 years ago

Answer:

To find the estimated sum, round the 2 integers to the nearest whole number.

12.3----->12

4.7------->5

we round 12.3 to 12 because whenever we're asked to round a number, we always look to the digit to the right of the number, if the digit on the right is greater than or equal to 5, we round up if it's less that 5, we round down.

12+5=17

12.3-4.7

we already rounded 12.3 to 12 and 4.7 to 5 so now

12-5=7

Hope this helps

Solve for X, 132 is an exterior angle. Show work please!
Darina [25.2K]

Answer:

105/9

Step-by-step explanation:

180 - 132 = 48 degrees

180 - 48 - 45

= 180 - 93

= 87 degrees

<2 = 180 - 87

= 93 degrees

=> 9x - 12 = 93

=> 9x = 105

=> x = 105/9

Write the tangent, cosine and sine ratios of angles X &amp; Y. Write each answer as a (reduced) fraction. Not a decimal.
Alisiya [41]

The tangent, cosine and sine ratios of angles X & Y in the reduced faction form is 3/4, 4/5 and 3/5 respectively.

<h3>What are the trigonometry ratios?</h3>

For a right angle triangle, the trigonometry ratios can be given as,

\rm \sin \theta=\dfrac{b}{c}\\\rm \cos \theta=\dfrac{a}{c}\\\rm \tan \theta=\dfrac{b}{a}

Here, <em>a</em> is base side<em>, b</em> is perpendicular side and<em> c</em> is the hypotenuse side of the triangle.

In the given triangle, the length of base side<em> </em>is 8 units, perpendicular side is 6 units and hypotenuse side is 10 units.

a=8\\b=6\\c=10

Thus, the  tangent, cosine and sine ratios of angles X & Y are,

\rm \sin \theta=\dfrac{6}{10}=\dfrac{3}{5}\\\rm \cos \theta=\dfrac{8}{10}=\dfrac{4}{5}\\\rm \tan \theta=\dfrac{6}{8}=\dfrac{3}{4}

Thus, the tangent, cosine and sine ratios of angles X & Y in the reduced faction form is 3/4, 4/5 and 3/5 respectively.
