Answer:25°
Step-by-step explanation:
One angle =130°
An isosceles triangle has two equal angles
Sum of angles in a triangle is 180°
Let the other two angles in The isosceles triangle be y°
130+y+y=180
Collect like terms
y+y=180-130
2y=50
Divide both sides by 2
2y/2=50/2
y=25
There other two angles in The isosceles triangle are 25° each
