Answer:

-1

Step-by-step explanation:

1. To simplify this expression, let's go through the steps of BODMAS.

  • \frac{(-2)^2(3)}{-9-5+2}
  • \frac{(4)(3)}{-9-5+2}
  • \frac{12}{-9-5+2}
  • \frac{12}{-14+2}
  • \frac{12}{-12}
  • -1

Therefore, the answer is -1.

A pentagon has angle measures of 12x°, 7x°, 16x°, 9xº, and 10x°. Find the<br> value of x.
8_murik_8 [283]

Answer:

10

Step-by-step explanation:

The sum of all the interior angles of a pentagon is 540°

So...

540 = 12x + 7x + 16x+ 9x + 10x

Combine like terms:

540 = 12x + 7x + 16x+ 9x + 10x

540 = 54x

Divide by 54 on both sides:

540 = 54x

/54     /54

10 = x

Hope this helps :)

Anyone helppp meee please ....

Yep, this one seems sneaky and confusing.  But it's not so bad if you remember the things you learned about parallel lines.  (It can't be too tough ... I learned them
in 1954 and I still know how to use them.)

Look at the picture.  Line ' l ' is parallel to line ' m ', and the horizontal line on the bottom (which is not labeled) is a transversal that cuts the parallel lines.

Did you learn that interior angles on the same side of the transversal are equal ?
I'm sure you did, although it may have a new name nowadays.

Anyway, with the help of that 'tool', angle-'B' and angle-'D' are equal.  So . . .

(angle-A + angle-B) = 120

angle-B = 65

angle-A = 120 - 65 = <u>55 degrees</u>.
