Step-by-step explanation:
All angles in a triangle add up to 180º, so we can make this equation.
7x-2+5x-10+4x=180
Combine like terms
16x-12=180
Add 12
16x=168
Divide
x=16.5

Answer:
Area = (a² -5a) in²
Perimeter = (4a -10) in
Step-by-step explanation:
Let the length of the rectangle be a.
Given that, its width is 5 in less than the length.
So,
length ⇒ a
width ⇒ (a - 5)
First, let's find the area of the rectangle.
Area = length × width
Area = a ( a - 5 )
<em>Solve the brackets.</em>
Area = <u>(a² -5a) in²</u>
<u />
Now, let us find the perimeter of the rectangle.
Perimeter = 2 ( l + w )
Perimeter = 2 ( a + a - 5 )
Perimeter = 2 ( 2a - 5 )
Perimeter = <u>(4a -10) in</u>
