(10 + 3x)° + (x - 30)° = 180°
(3x + x)° + (10 - 30)° = 180°
4x° - 20° = 180°
4x° = 180° + 20°
4x° = 200°
x° = 200/4
x° = <u>50°</u>
So, the value of x is 50°

Answer:
3 in
Step-by-step explanation:
Sum of all sides of ∆ = perimeter
Given that it has a perimeter of 13 in, and the following sides: (x - 5) in, x/2 in, and 6 in, therefore:
Solve to find the value of x
Multiply both sides by 2
Subtract 2 from both sides
Divide both sides by 3
The shortest side = (x - 5) in
Plug in the value of x
= (8 - 5) in
= 3 in
