A non negative angle which is less than 90 degrees is an acute angle. So, Zero degree is an acute angle.
Is 65 an acute angle
An acute angle.
Well since an acute angle is everything with a smaller degree than a right angle, there is no perfect acute angle. However, to demonstrate an acute angle, i would go with around a 20-25 degree angle.
A 40 degree angle is an acute angle, since all angles less than 90 are acute.
An acute angle
Based on the limited context provided by the question, it is an acute angle.
It is an acute angle
It is an acute angle.
A non negative angle which is less than 90 degrees is an acute angle. So, Zero degree is an acute angle.
A 22 degree angle is an acute angle
Is 65 an acute angle
An acute angle.
Example: Express sin 120⁰ as a function of an acute angle (an angle between 0⁰ and 90⁰).Solution:Each angle θ whose terminal side lies in quadrant II, III, or IV has associated with it an angle called the reference angle, alpha (alpha is formed by the x-axis and the terminal side).Since 120⁰ lies on the second quadrant, then alpha = 180⁰ - 120⁰ = 60⁰.Since sine is positive in the second quadrant, sin 120⁰ = sin 60⁰.Example: Express tan 320⁰ as a function of an acute angle.Solution:Since 320⁰ lies on the fourth quadrant, then alpha = 360⁰ - 320⁰ = 40⁰.Since tangent is negative in the fourth quadrant, tan 320⁰ = -tan 40⁰.
an acute angle measure from 1 degree to 89 degrees
A 12 degree angle is an acute angle.
A 73 degree angle is an acute angle
