Some of the devices used to measure angle are Transit, Protractor and Compass.

There's the protractor, a bevel gauge, and the plain ol' measuring tape with pen and paper.Inclinometer.
To find the measurement of angle A in the triangle, we can use the fact that the sum of the angles in a triangle is always 180 degrees. Given that angle E measures 30 degrees, angle F measures 57 degrees, and angle B measures 27 degrees, we can calculate angle A as follows: Angle A = 180 - (angle E + angle F + angle B) = 180 - (30 + 57 + 27) = 180 - 114 = 66 degrees. Therefore, angle A measures 66 degrees.
if an angle measures 30 then it is acute
A sextant.
Protractors

An ergometer measures work in science terms.
A protractor measures degrees: 90, 80, 120 etc. If something is 90 degrees it is at a right angle
universal bevel protactor is an angle measuring instrument which measures acute angle ,obtuse angle as well as it is used to layout an angle. its least count is 5 minute.
This work is commonly accomplished by a thermometer.

An angle that measures 210 degrees is a reflex angle.
A right angle measures 90 degrees
The third angle measures 18 degrees.
To find the measurement of angle A in the triangle, we can use the fact that the sum of the angles in a triangle is always 180 degrees. Given that angle E measures 30 degrees, angle F measures 57 degrees, and angle B measures 27 degrees, we can calculate angle A as follows: Angle A = 180 - (angle E + angle F + angle B) = 180 - (30 + 57 + 27) = 180 - 114 = 66 degrees. Therefore, angle A measures 66 degrees.
