Find the value of sinY

Mathematics

Tatiana [17]3 years ago
8 0

Answer:

\frac{63}{65}

Step-by-step explanation:

Please see the attached picture.

Let's find the value of the opposite side, XZ.

Applying Pythagoras' Theorem,

(XZ)² +(XY)²= (ZY)²

(XZ)² +16²= 65²

(XZ)²= 4225 -256 <em>(</em><em>bring</em><em> </em><em>constant</em><em> </em><em>to</em><em> </em><em>1</em><em> </em><em>side</em><em>)</em>

(XZ)²= 3969 <em>(</em><em>simplify</em><em>)</em>

<em>Square</em><em> </em><em>root</em><em> </em><em>both</em><em> </em><em>sides</em><em>,</em>

XZ= \sqrt{3969}

XZ= 63 <em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>(simplify)</em>

sinY

= XZ/ ZY

= \frac{63}{65}

Shkiper50 [21]

Answer:

$246

Step-by-step explanation:

The price of the product is $390, after 6 months the price is marked down by 10% which is $39 so the total will be $351. After another 6 months the price is marked down again by 30%, which is $105 and 3 cents ($105.3). For a total of $245 and 7 cents ($245.7).  To round the number you only need to look at the number after the decimal which is 7 in this case. Any number bellow 5 counting 5 in it, will stay the same number, any number above 5 without counting 5 will be the next number. So $245.7 rounded to the nearest dollar will be $246.

Hope it was helpful ^^ <3

Good Luck

On a survey, 7 students reported how many minutes it takes them to travel to school. Here are their responses.
Svetradugi [14.3K]
To find the average, add them all up. 13 + 7 + 12 + 9 + 8 + 8 + 16 = 73
Then divide by how many numbers there are, 73 divided by 7 = 10.4285714286

10.4285714286 rounded to the nearest tenth = 10.4
Hope this helps :D
