Answer:
Step-by-step explanation:
First, remember that the maximum degree of an angle totals 360°.
Since we already have 294°, this means that what is left must total 
.
Therefore, this means that our two smaller angles must equal 66°. So:
Solve for x. Add on the left:
Subtract 8 from both sides. Therefore, the value of x is:
2x+38=180
2x=142 (or x+x=142 from which 2x=142)
x=71
The unknown angles are each 71
You know this answer is logical as, since two sides are 21 it hints that we are looking at an equilateral triangle, which means two of its angles will be the same
