To find the measure of angle A in a right triangle with sides a = 400 feet and b = 900 feet, we can use the tangent function: ( \tan(A) = \frac{a}{b} = \frac{400}{900} ). Calculating this gives ( \tan(A) \approx 0.4444 ). Taking the arctangent, we find ( A \approx 26.57^\circ ), which rounds to approximately 27 degrees.
To find the degree of angle of a side of a triangle, a protractor is needed to measure the angle. Place the '0' on the protractor on the point of the angle and look at the top part to determine degree of angle. To measure the length of a triangle side, a simple ruler can be used to measure the length.
A right angle
You cannot. An angle of a triangle can have any value between 0 and 180 degrees.
To find the measure of angle A in the right triangle, we can use the tangent function: ( \tan(A) = \frac{b}{a} ). Substituting the given values, we have ( \tan(A) = \frac{39.3}{76.4} ). Calculating this gives ( A \approx \tan^{-1}(0.514) ), which is approximately 43 degrees. Thus, angle A is approximately 43 degrees to the nearest degree.
90 degrees
You can measure it. Or you can measure some other quantities (for examples, the lengths of the sides of a triangle), and calculate the angle using trigonometry.
