PLZ FAST I DONT WANNA DIE

Mathematics
1 answer:
gavmur [86]3 years ago
6 0

Answer:

x=15

Step-by-step explanation:

<GCB=180-5x

<EBA=9x

<DAC=8x

The sum of the three exterior angles equals 360.

(180-5x)+9x+8x=360

180-5x+9x+8x=360

-5x+9x+8x=360-180

12x=180

x=15

Answer:

Pretty Simple!

Now that you know about ratios and all that, this is pretty tame compared to the last problem.

Now, the problem is talking 2D(2 Dimensions)

The ratio is not going to work because it has only one parameter.

Thus, we need to square it!

(\frac{1}{20})^{2}  =\frac{1}{400}

Thus, we have your correct ratio.

Now, we only need to do the same thing for the triangle problem. Meaning that, we need to compare the ratios, with x as the thing we are looking for.

\frac{1}{400}=\frac{219}{x} \\x=87,600

See? X is practically handed to us.

Hope this helps!

Add. Simplify the answer to lowest terms before entering the numerator and denominator in their boxes. 11/16 + 3/16
myrzilka [38]

Answer:

The answer is 7/8.

Step-by-step explanation:

If you add 11/16 to 3/16, you'll get 14/16.  14/16 has two numbers that are divisible by 2,  so when you divide 14/16 by 2 you'll get 7/8 which is 14/16 in a simplified form.  7 is prime and you can't divide it down any more, but 8 i'snt the same way.  The rule is, whatever you do to one side, you have to do to the other.  You can divide 8, but not 7; therefore, you cannot simplify the fraction any further.

Answer:

X = 4

Step-by-step explanation:

In the equation add 3 to both sides of the equation

1/2x-3+3=2-3/4x+3

Simplify

1/2x = -3/4x + 5

Add 3/4x to both sides

1/2x + 3/4x = -3/4x + 5 + 3/4x

Simplify

5/4x=5 Multiply both sides by 5

5x=20 divide both sides by 5

5x divided by 5 and 20 divided by 5

=4
