Find the area of the parallelogram.
tensa zangetsu [6.8K]

Answer:

<h2>A = 210 cm²</h2>

Step-by-step explanation:

Area of a parallelogram = base × height

From the question

The base is = 30 cm

Let h represent the height of the parallelogram

We must first use Pythagoras theorem to find the height of the parallelogram before finding it's area

We have

{25}^{2}  =  {h}^{2}  +  {24}^{2}  \\  {h}^{2}  =  {25}^{2}  -  {24}^{2}  \\  {h}^{2}  =  \sqrt{ {25}^{2}  -  {24}^{2} }  \\  {h}^{2}  =  \sqrt{625 - 576}  \\  {h}^{2}  =  \sqrt{49}

We have the answer as

h = 7 cm

So from the question

height = 7cm

Let's substitute the base and the height into the above formula and solve for the area

We have

Area = 30 × 7

We have the final answer as

<h3>A = 210 cm²</h3>

Hope this helps you

ch4aika [34]
Hello!

We must use muliplication to solve this question because when we multiply the amount chickens Adrian eats by the amount of fries he eats, it will result in the answer.

7 fries × 4 chickens = 28 Fries

So, Adrian will eat 28 fries.

If sin(x) = cos(y) for acute angles x and y, how are the angles related?
Vesnalui [34]

Answer:

b. complementary

Step-by-step explanation:

-Complementary angles are angles that add up to 90°.

-These are usually the two acute angles in the right triangle.

#To verify, lets take the two angles 30° and 60°:

Cos \ 60\textdegree=0.5\\\\Sin \ 30\textdegree=0.5\\\\\therefore Sin \ 30\textdegree=Cos \ 60 \textdegree=0.5

#We can reverse as:

Sin \ 60\textdegree=0.86603\\\\Cos \ 30\textdegree=0.86603\\\\\therefore Sin \ 60\textdegree=Cos \ 30\textdegree=0.86603

Hence, two angles are said to be complimentary if they sum up to 90°.
