The answer is A) Right because the lengths 3 cm and 3 cm are obviously the same so it will form a right angle

Answer:

Acute.

Step-by-step explanation:

This is a right angle:

|_ (Basically angle makes an "L" shape and equals to 90 degrees)

This is an obtuse angle:

\_ (Basically like a fat/big angle that is greater than 90 degrees)

This is an acute angle:

/_ (Basically "a-cute" angle that is small and is less than 90 degrees)

A game costs $39.00. But the new special edition version is going to be $56.94. What is the increased percent?

astraxan [27]

Answer:

46%

Step-by-step explanation:

Step 1: Make an expression

$39.00 * x = 56.94$

$39x = 56.94$

Step 2: Divide both sides by 39

$39x / 39 = 56.94 / 39$

$x = 1.46$

Step 3: Find the percent

$1.46 - 1$ -> Gives us the increased percent

$0.46 * 100$

46%

Answer: 46%

The city will place a low fence around the entire fish pond.To the nearest hundredth, how long will the fence be?

Tom [10]

You can't tell the dimensions from the area. There are an infinite number of correct answers. The length of the fence is 2 times (length of the pond + width) and the length and width can be anything, just as long as their product is 2956.5 .

Find the missing part.

Answer:

The answer is $a = \frac{15}{4}$

Step-by-step explanation:

We have to:

$cos(\theta) = \frac{adjacent\ side}{hypotenuse}$

So, if we take the 60 degree angle of the smallest triangle, we have to:

$cos(60) = \frac{a}{x}$

We do not know x. But if we take the sine of the angle of 30 degrees and the main triangle we have:

$sin(30) = \frac{x}{15}\\\\x =\frac{15}{2}$

Then:

$cos(60) = \frac{a}{\frac{15}{2}}$

$a = cos(60)\frac{15}{2}$

$a = \frac{15}{4}$
