The spacing in the question makes it difficult to be sure of the information.
I am assuming
angle 1= x - 15
angle 2 = 2x - 165
angle 3 = 90
Assuming the relevant shape is a triangle, then
angle 1 + angle 2 + angle 3 = 180
so x - 15 + 2x - 165 + 90 = 180
3x - 90 = 180
3x = 270
x = 90.
A right angle is an angle of 90 degrees.
A 90-degree angle is a right angle.
A 90-degree angle is commonly called a right angle.
<90 is an Acute angle =90 is a Right angle >90 is an Obtuse angle
A 90 degree angle is a right angle.
When the angle = 90 degrees, it is a Right Angle. When the angle is greater than 90 degrees, it is an obtuse angle.
An angle of 90 degrees is normally called a right angle.An angle of 90 degrees is a right angle
A 90 degree angle is a right angle but an acute angle is less than 90 but greater than 0 degrees.
No that is a right angle. An obtuse angle is any angle over 90 degrees.
A right angle. i think it's a right angle
Right angle (90) Acute angle (<90) Obtuse angle (>90) Straight angle (180) Reflex angle (>180)
right angle
