Answer: 90° , 60° and 30° .
Step-by-step explanation:
Given : In a right triangle with a leg of 4 units and a hypotenuse of 8 units.
One angle should be 90°. (A right triangle has a 90° angle.)
Let the given leg is the side opposite to the angle in the triangle.
Then by trigonometry , we have
[Sine of an angle is the ration of the side opposite to the angle and the hypotenuse of a right triangle.]
Also ,
Let x be the measure of the third angle.
BY Angle sum property of triangle , we have
Therefore , the measures of all angles in the triangle : 90° , 60° and 30° .
So to find how many tenths, or 1/10's, there are in four fifths, or 4/5, divide 4/5 by 1/10.
Now, remember that <u>dividing by a number is equivalent to multiplying by its reciprocal</u>. To find the reciprocal, just flip the numerator and denominator around. In this case, 1/10 would become 10/1. Flip 1/10 to its reciprocal, change the sign to multiplication, and multiply numerators with numerators and denominators with denominators:
<u>In short, there are 8 tenths in four fifths.</u>
