Supplementary angles add up to 180 degrees
The value of x is 17
The given parameters are:
Because the angles are supplementary, then:
So, we have:
Collect like terms
Divide both sides by 8
Hence, the value of x is 17

100=r( x) This could possibly be correct I really have no idea
Answer:
sum of interior angles - 540
x = 112
Step-by-step explanation:
Hello There!
<u>Geometry</u>
The sum of the interior angles can be found using this formula
let x = sum of interior angles and n = number of sides
x = ( n - 2 ) * 180
there are 5 sides so we plug in 5 to n
5 - 2 = 3
3 * 180 = 540 so the sum of the interior angles is 540
Now to solve for x
Remember the sum of the interior angles is 540 so we use this equation to solve for x
<u>Simple Algebra</u>
540 = x + 118 + 105 + 75 + 130
step 1 combine like terms
118 + 105 + 75 + 130 = 428
now we have 540 = 428 + x
step 2 subtract 428 from each side
540 - 428 = 112
we're left with x = 112

Determine the relationship between both triangles
The single line on all sides of both triangles implies that the sides of the triangles are equal
i.e.
--- sides
Similarly, the same mark on the three angles of both triangles means that the angles of the both triangles are equal
i.e.
--- angles
<em>Hence, both triangles are congruent</em>
