Remark
Three angles add to 180o.
The smallest angle = x
The middle angle = 2x
The largest angle = 3x
Solve
x + 2x + 3x = 180
6x = 180
x = 180 / 6
x = 30
Answers
The smallest angle is 30
The middle angle is 30*2 = 60
The largest angle is 30*3 = 90
This is a 30 - 60 - 90 right triangle
Answer:
Width is 20cm
Step-by-step explanation:
Step one:
Given data
let the width be x
W= x
L= x+5
P= 90
Step two:
The expression for the perimeter is
P= 2L+2W
90= 2*x+2(x+5)
90= 2x+2x+10
collect like terms
90-10=4x
80= 4x
divide both sides by 4
x= 80/4
x= 20
