Answer:

Step-by-step explanation:

Firstly, find the total amount of pens

5 + 10 + 20 = 35, Total of 35 pens

White pens: 10/35

Not a red pen: 20 + 10= 30, 30/35

Calculate these to a percentage:

White- 10/35: 28.57%

Not a red pen- 30/35: 85.71%

Angle 6 and Angle 7 are each 90° since they’re on a straight line and are both equal.
180-90= 90
*you subtract from 180 because that’s how many degrees are in a straight line*
Angle 7 and Angle 1 are alternate exterior angles so that makes them congruent by definition.

Step-by-step explanation:

=>>. Hello mate. (◕ᴗ◕✿)

= Given :-

perimeter of traingle = 58 feet

 let the third side be. "X" feet

  longest side = (2x - 8) feet

 shorter side = (x + 2) feet

Perimeter of traingle = sum of all three sides

=> A/q. ,

( x ) + ( 2x - 8 ) + ( x + 2) = 58. ✓✓✓

 x + 2x - 8 + x + 2 = 58

=>. 4x - 6 = 58

=> 4x = 58 + 6

=> 4x = 64

=>. x = 64/4

 =|. x = 16 feet

length of third side = 16 feet

length of shorter side = 18 feet

length of longest side = 24 feet

 Hope it helps you.......
