Answer:135 degrees
Step-by-step explanation:
it is an isosceles triangle where 2 sides and angles are equal.
Given: one side is 90 degrees the other 2 are 45 each to make 180 degrees.
A straight angle is 180 degree and 180-45=x=135 degrees
Answer:
x=135°
Step-by-step explanation:
as an isosceles right angled triangle,other angles other than 90°
will be same (let them be y)
2y+90°=180°(angle sum property)
2y=90°
y=45°
x+y=180°
x+45°=180°
x=180°-45°
x=135°
