Answer:
The answer is 98
Step-by-step explanation:
Subtract the sum of the two angles from 180 degrees.
The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.
62+20=82
180-82=98
98+20+62=180
1_ 210+90= 300
2_ it's prime:
[1,19]
