A triangle has sides 8cm and 5cm and angle of 90° between them . Calculate the smallest angle of the triangle

30º

Step-by-step explanation: Draw a line of 5cm. Draw another line at an end that is 8cm and has an angle of 90º between them. Join the ends of the lines. Measure the smallest angle and it should be 30º.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
