Answer:
61°
Step-by-step explanation:
This is an isosceles triangle, because the two adjoining sides show 6 as their length. Since an isosceles triangle has two sides of same length, the other angle which is not labelled also has the same value of x.
That means:
x + x + 58 = 180°
2x + 58 = 180°
2x = 180° - 58
2x = 122°
x = 122/2
x = 61°
P.S. Hope you know that in a triangle, all angles add to 180°. Hope this helps!
