Question

HELP ASAP! Thank you!

Answer 1

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

      ⇒ $x + x +70 = 180$

Let's solve:

 $x+ x + 70 = 180\\2x + 70=180\\2x=110\\x=55$

Answer: 55

Hope that helps!
