find the missing part.

1) To find  we are going to use the Pythagorean equation:
 
where 
and  are the legs of our triangle. For our picture we can infer that  and , so lets replace those values in our equation to find :




We can conclude that the value of  in our triangle is 12.8

2) To find  we are going to use the trigonometric function tangent. Remember that . We know that the opposite side of our angle  is 8, and its adjacent side is 10, so lets replace those values in our tangent function to find :


Since we need the measure of angle , we are going to take inverse tangent to both sides to find it:


We can conclude that the value of  in our triangle is 38.66°

3) Finally, to find  we are going to take advantage of two facts: the sum of the interior angles of a triangle is always 180°, and  our triangle is a right one, so one of its sides is 90°. Therefore, . Since we already know the value of , lets replace it in our equation and solve for :



We can conclude that the measure of angle  is 51.34°

Yeah she/ he needs look how long that is man
