<h3>What is an angle?</h3>
An angle is formed by the intersection of two or more lines. Types of angles are acute, obtuse and right angled.
From the diagram:
∠EGB and ∠AGF are congruent (vertical angles therorem).
∠AGF and ∠CHF are corresponding and congruent according to the Corresponding Angles Theorem
∠EGB and ∠CHF are congruent by the Transitive Property of Equality

Answer:
11 - 125 and 55
12 - supplementary
Step-by-step explanation:
5x+20+3x-8=180
step 1 combine like terms
8x+12=180
step 2 subtract 12 from each side
8x=168
step 3 divide each side by 8
x=21
then you just plug in 21 to each equation to find that angle 1 = 125 and angle 2=55
The answer is 1/3x + 2/4 .
In order to find the perimeter, all we have to do is add all three of the sides:
x^2 + 3 + 2x + 5 + 2x = 29
x^2 + 4x + 8 = 29
Subtract 29 from both sides:
x^2 + 4x - 21 = 0
Factor:
(x + 7)(x - 3) = 0
{-7, 3}
3 can be the only possible length, since a length can't be a negative number.
2x = 6
2x + 5 = 11
x^2 + 3 = 12
