The sum of all interior angles in a polygon is

180(n - 2), where n = "number of sides in the polygon"

now, this polygon has 5 sides, so is a PENTAgon, so the sum of all its interior angles is 180( 5 - 2), or  540.

we know 4 of them, so the last one, the one next to A, has to be 540 - 104 - 118 - 96 - 115, namely is 107.

now, notice, that angle is next to A, is really sitting on the same exact line angle A is sitting on, so that angle is a linear angle with A.

what the dickens does that mean?  well, linear angles make up 180°, therefore,

107 + A = 180
A = 180 - 107

marin [14]

Answer:

12.1072

Step-by-step explanation:

 5.264

x                           take 3 multiply with 5264 = 15792

      2.3                 then take 2 multiply with 5264 = 10528

 15792                  add column by column as drop 2 down, then 9 + 8

10528                    then 7+2, 5+5, 1+0, 1. then count how many numbers total

121072                  behind the point  .264= 3 numbers + .3 is 1 number= 4#s

                               then count backward the result 4 numbers 2701 put the                        

                               dot there you will get 12.1072

Tom's property has a shape of a parallelogram with the dimensions of l= x +75 and w= x + 45. If the perimeter is 300 feet, what
scZoUnD [109]

Answer:

15 feets

Step-by-step explanation:

The perimeter of a parallelogram is given as :

P = 2(l + w)

l and w are the bases :

Substituting the values into the equation :

P = 2(x + 75 + x + 45)

P = 2(2x + 120)

P = 300

Hence ;

300 = 4x + 240

300 - 240 = 4x

60 = 4x

Divide both sides by 4 to isolate x

60 /4 = 4x / 4

15 = x

x = 15 feets

It would be appreciated if there could be an explanation along the answer
soldi70 [24.7K]

Answer:

i think probably 80°

Step-by-step explanation:

PQ = RS

2x+3 = 4x-3

x = 3

PTQ = RTS

9y-3x-1 = 5x+7y-5

2y-8x = -4

y-4x = -2

y-4(3) = -2

y-12 = -2

y = -2+12

y = 10

so PTQ = 9y-3x-1

9(10)-3(3)-1

90-9-1

80°
