Answer:
20 degree angle
Step-by-step explanation:
Each angle of the triangle added together must be equal to 180, so 53+45=98. 180-98=82. So the top angle is 82, the value of x has to be equal to 180-82 which equals 98
If lines a and b are parallel, the two angles given would be the same.
2x - 5 = x + 20
x = 25
The answer is 46 thank you
