The value of a is 5 units if in the right triangle with an acute angle of 30 degrees option (D) 5 is correct.
What is a right-angle triangle?
It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.
The missing figure is attached to the picture, please refer to the picture.
To find the value of using the sin ratio:
sin30 = a/10
a = 10sin30
As we know sin30 = 1/2
a = 10(1/2)
a = 5
Thus, the value of a is 5 units if in the right triangle with an acute angle of 30 degrees option (D) 5 is correct.
