as we all know ... an octagon has 8 corners / sides

and they told that each side is equal to 2a + 1

so we need to make an equation which will be 8 (2a+1)

ans now we need to multiply 8 with both 2a and 1

so, 8 ( 2a + 1 )

16a + 8

we cant do this further as its not "like"

so the answer is 16a + 8

The ratio of three angle are 3:4:5 what is the highest angle of the triangle??

SCORPION-xisa [38]

The sum of the sides of a triangle is equal to 180º.
The three angles will be: 3x,4x and 5x.
we can suggest the following equation:
3x+4x+5x=180

12x=180
x=180/12
x=15

The angles would be:
3x=3(15)=45
4x=4(15)=60
5x=5(15)=75

Answer: the highest angle would measure 75º.
