Answer:
the answer is c)SAS
Step-by-step explanation:
as the sides are already given and and both angles will be equal as vertically opposite angles (VOA)are always equal.
Answer:
x = 23°
Step-by-step explanation:
Looking at the diagram above, we can see that it is Pentagon.
The sum of interior angles in a Pentagon (5 sides polygon) = 540°
This is because in a Pentagon, from the vertex we can draw 2 diagonals that would result in 3 triangles.
Sum of angles in a triangle = 180°
Hence, the sum of angles in a Pentagon = 3 × 180°
= 540°
Hence,
540° = 85° + 5x° + 5x° + 5x + 5° + 5x - 10°
540° = 85° + 5° - 10°+ 5x° + 5x° + 5x° + 5x°
540° = 80° + 20x°
540° - 80° = 20x°
460° = 20x°
x° = 460/20
x = 23°
Therefore, the value of x = 23°
9 inches, divide 108 by 12, because 12 inches makes a foot
For a, x is equal to the sum of the measures of the inside angle because the total degrees of a triangle is 180 and the total degrees of a line is 180. Since both the line and the triangle are missing the same amount, x would equal the interior degrees that are listed. I don’t know what m<x means for b, but if it’s asking for the value of x it’s 62+78= 140° which makes the missing interior angle 40°. Hope this helps!
