Answer
Step-by-step explanation
To answer this, we need to note that the base angles of an isoscelles are equal to each other. So,
Angle J = Angle M
Angle J = 17x + 7
Angle M = 14x + 10
17x + 7 = 14x + 10
17x - 14x = 10 - 7
3x = 3
Divide both sodes by 3
(3x/3) = (3/3)
x = 1
Angle J = 17x + 7 = 17(1) + 7 = 17 + 7 = 24°
Angle M = 14x + 10 = 14(1) + 10 = 14 + 10 = 24°
Then, we know that the sum of angles in a triangle is 180°
So,
