Answer:

140

Step-by-step explanation:

Consider a square for just a second. It has 4 angles each of 90 degrees. The total number of degrees in a square is 4 * 90 = 360.

It should be at least an appeal to your intuition to say that a quadrilateral has a total of 360 degrees.

Therefore the ratio you have been given must have 4 angles that add to 360.

2x + 3x + 6x + 7x = 360

18x =360

x = 20

So the 4 angles are

2* 20 = 40

3*20 = 60

6*20 = 120

7*20 = 140

Total 360

The largest angle is 140

Solve the formula for the specified variable<br> A=p+prt solve for r

soldi70 [24.7K]

Answer:

Step-by-step explanation:

The first step is to take p on both sides:

$A - p = p + p*r*t - p$

On the right hand side, cancel p and -p, since $p-p=0$ . The equation will be:

$A - p = p*r*t$

Then, divide both sides of the equation by p*t:

$\frac{A-p}{p*t} = \frac{p*r*t}{p*t}$

On the right hand side, p*t can be cancelled:

$\frac{A-p}{p*t} = r$

Which algebraic expression represents the difference of e squared and twenty-one? A. E2+21 b.21 times e2 c. E2 - 21 d. 21 divide

Digiron [165]

Answer: c. E2 - 21

Step-by-step explanation:

difference means to subtract

Now, e squared=E² and twenty-one=21

Therefore the difference of e squared and twenty-one is E2 - 21
