With this, we should remember SOHCAHTOA (Sine: Opposite over Hypotenuse, Cosine: Adjacent over Hypotenuse, and Tangent: Opposite over Adjacent).

Using the image attached, we know that we should use Sine, because we know the hypotenuse (100 feet) and we want to know the height, or the Opposite (h).

So, we use: sin(48)=h/100 and we multiply both sides by 100 to get:

100sin(48)=h

Now, we just plug the numbers into a calculator. (Make sure your calculator is set to Degrees, or "Deg").

What we get is about 74.3144825... but we can round that to 74.3 feet.

Answer: 74.3 feet.

An artist designed a badge for a school club. Figure ABCD on the coordinate grid below shows the shape of the badge.
dedylja [7]

Answer:

(8, 4)

Step-by-step explanation:

<em>AD is enlarged to JM</em>

<em>AD² = 2² + 1² = 4 + 1 =5</em>

<em>AD =  √5</em>

then you plug in JM

<em>JM² = 6² + 3² = 36 + 9 = 45</em>

<em>JM = √45 = 3 √5</em>

<em>so if </em>

<em>JM=3 AD</em>

then

<em>ML= 3 DC </em>

<em>then you add</em>

<em>5+3=8</em>

the coordinates for point L are (8, 4)

Which expression represents this word phrase?<br><br> five more than the product of x and 6
disa [49]

<u><em>Answer:</em></u>

<u>The expression is:</u> 6x + 5

<u><em>Explanation:</em></u>

Product means <u>multiplication</u>

Therefore, the product of x and 6 means that we will multiply x by 6

<u>This would give us:</u> 6x

Now, five more than the product means that we will <u>add</u> 5 to the product we just obtained

<u>This means that:</u>

<u>five more than the product of x and 6 is:</u>

6x + 5

Hope this helps :)
