16 divided by 28 is different as 9 divided by 21 => it is wrong

  • 48 centimeters by 27 centimeters

16 divided by 48 is different as 9 divided by 27 => it is wrong

  • 26 inches by 19 inches

16 divided by 26 is different as 9 divided by 219=> it is wrong

coldgirl [10]

Answer:

Since there are already 2 angles shown, which are 48 and 90 (indicated by the square in the bigger triangle, we can set up an equation.

48 + 90 + y = 180

138 + y = 180

-138 + 138 + y = 180 - 138

y = 42°

The legs of a scalene triangle are represented by (x + 4), (x + 8), and ( 2x − 3). Which polynomial expression BEST represents t
ivanzaharov [21]

The perimeter of the triangle is: 4x+9

Step-by-step explanation:

Perimeter is the measurement of boundary of any closed figure.

Given

s1 = x+4

s2 = x+8

s3 = 2x-3

So, the perimeter will be the sum of all three sides

P = s_1+s_2+s_3\\= (x+4) + (x+8) + (2x-3)\\= x+4+x+8+2x-3\\= 4x+9

Hence,

The perimeter of the triangle is: 4x+9

Keywords: Perimeter, triangle
