from the image given, all three angles are equal to each other
from the first triangle, we have two sides i.e 27 and 95 degrees.
remember that sum of angles in a triangle is equal to 180 degrees
27 + 95 + x = 180
x = 180 - 122
x = 58
the second triangle has to sides given which are 27 and 58 degrees
repeat the same process again
27 + 58 + x = 180
x = 180 - 85
x = 95
the third angle also has three sides given which are 95 and 58 degrees
repeat the same process we've done above
95 + 58 + x = 180
x = 180 - 153
x = 27
note how all the missing sides always corresponds to the other sides of the triangle.
