Answer:

A)\ [-3+ (6-8)] - [40+ (5.3-7) +20.2] = -63.5

B)\ -4 + [- 2.6-1 - (- 3.4)] + (- 5) * (- 3) + (- 10) =0.8

C)\ -22 * \{- 5+ [8.3- (3.6-9)]\} - (- 2) * (3) =-185.4

D)\ -9 - (- 2 + 5) * [- 3 + (- 5) - (+ 2) +1] =18

E)\ 40 * \{- 12 * [4 + (- 6) * (- 5) -15.3 + 12]\} - 2 =-14738

F) -21 * \{- [- 6 * (7-3)] - (7.6-8.3)\} - 89 =-607.7

Step-by-step explanation:

A)\ [-3+ (6-8)] - [40+ (5.3-7) +20.2] =

Resuelve todas las expresiones en el paréntesis interior

[-3-2] - [40 -1.7 + 20.2]

Resuelve cada paréntesis

-5 - 58.5

-63.5

B)\ -4 + [- 2.6-1 - (- 3.4)] + (- 5) * (- 3) + (- 10) =

Resuelve todas las expresiones en el paréntesis interior

-4 + [-0.2] + (- 5) * (- 3) + (- 10)

Resuelve todas las multiplicaciones y paréntesis.

-4 -0.2 + 15-10

=0.8

C)\ -22 * \{- 5+ [8.3- (3.6-9)]\} - (- 2) * (3) =

Resuelve todas las expresiones en el paréntesis interior

-22 * \{- 5+ [8.3 + 5.4]\} - (- 2). (3)

Resuelve todas las multiplicaciones y paréntesis.

-22 * 8.7 +6

-191.4 + 6

=-185.4

D)\ -9 - (- 2 + 5) * [- 3 + (- 5) - (+ 2) +1] =

Resuelve todas las expresiones entre paréntesis interiores

-9 - 3 * [- 3 - 5 - 2 +1]

-9-3 * -9

-9 + 27

= 18

E)\ 40 * \{- 12 * [4 + (- 6) * (- 5) -15.3 + 12]\} - 2 =

Resuelve todas las expresiones entre paréntesis interiores

40 * \{- 12 * [4 - 6 * - 5-15,3 + 12]\} - 2

Multiplicar -6 por -5

40 * \{- 12 * [4 + 30-15.3 + 12]\} - 2

Resuelve todas las expresiones en el paréntesis interior

40 *\{- 12 * 30.7\} - 2

Quitar todos los paréntesis

40 * -368.4 - 2

-14736 - 2 \\

=-14738

F) -21 * \{- [- 6 * (7-3)] - (7.6-8.3)\} - 89 =

Resuelve todas las expresiones entre paréntesis interiores

-21 * \{- [- 6 * 4] +0.7\} - 89

Multiplicar -6 por 4

-21 * \{24 +0.7\} - 89

Quitar todos los corchetes

-21 * 24.7 - 89

-518.7 - 89

=-607.7

What do I need to subtract from to get angle two?
ololo11 [35]
Step 1) Add up the three given angles: 125+109+83 = 317

Step 2) Subtract the result (found in step one) from 360
360 - 317 = 43

The reason for the 360 is because for any four-sided polygon, the angles always add up to 360 degrees. 

The answer is 43

Answer:

B. (-3, -17)

Step-by-step explanation:

Plotting them out on a graph, the other 3 points are able to be connected as a parallelogram. If you don't have graph paper at home, you can do an online search for "online graph paper" and use that. I personally find it very helpful to be able to see these kinds of things with my eyes.
