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
360=95+120+120+125+x+84+x
360=544+2x
-184=2x
x= -92
To solve, set an equation:
First Number: x
Second Number: 2x
x+2x=36
3x=36
divide both sides by 3
x=13
First Number: (x) 12
Second Number: (2x) 24
Answers: 12 and 24
Answer:
x = 19°
Step-by-step explanation:
Let The angle be "a"
Now according to the question,
⇒ 3 × a = (90° - a) - 14° (Then remove the brackets)
⇒ 3a = 90° - a - 14°
⇒ 3 + a = 76°
⇒ 40° = 76°
⇒ a = 76/4
Now since you got 76/4 you have to make it into simplest form so it'll be :
19/1
Your answer is : a = 19°
