Answer:
x = 55°
Explanation:
The given triangle has two equal sides each equals 5 units. This means that the given triangle is an isosceles triangle having one angle equals 70° and the other two angles are equal (each having a measure of x°).
Now we know that the sum of the interior angles of a triangle is 180. This means that:
180 = 70 + x + x
180 - 70 = 2x
110 = 2x
x = 110 / 2
x = 55°
Hope this helps :)
