Let's see what information we get from this picture:
First information
⇒ triangle is an isosceles triangle
⇒ meaning that the 'unlabeled angle' adjacent to 'angle of measure x'
⇒ are equal
Second information:
⇒sum of all the angle's measure of a triangle is 180 degrees
⇒ [tex]x + x +70 = 180[/tex]
Let's solve:
[tex]x+ x + 70 = 180\\2x + 70=180\\2x=110\\x=55[/tex]
Answer: 55
Hope that helps!
