  • a=115°(Alternate interior angles)
  • b=70°(Alternate interior angles

C:-

\\ \sf\longmapsto c+115=180

\\ \sf\longmapsto c=180-115

\\ \sf\longmapsto c=65°

D:-

\\ \sf\longmapsto d+70=180

\\ \sf\longmapsto d=180-70

\\ \sf\longmapsto d=110°

Answer:

  • a = 115°, alternate interior angles are congruent
  • b = 70°, same as above
  • c = 180° - 115° = 65°, angles forming a straight angle are supplementary
  • d = 180° - 70° = 110°, same as above

I need help I don’t know how to do it
daser333 [38]
If a line is drawn across the shape connecting two of the angles it makes two triangles. The sum of the angles in a triangle is 180 degrees.
Since this shape makes two triangles the sum of the inside angles is 2 * 180 = 360 degrees

(2x - 17) + 90 + x + 59 = 360
combine like terms
3x + 132 = 360
3x = 360 - 132
3x = 228
x = 76

julsineya [31]
Good afternoon, 

First side= 8cm 
Third side= x
Second side= 2x-4

We know that the sume of the lenghts of any two sides must be greater than the third side, so:

Second \,\,\,\,side+Third\,\,\,\,side>First\,\,\,\,side \\ 2x-4 + x >8 \\ 3x>12 \\ x>4


<span>Answer: Third side= x                        ;         where: x>4 or (4,+infinity)
                Second side= 2x-4              ;        </span><span> where: x>4 or (4,+infinity)</span>
