b.vertical height through which he rises.

4 answers

cool right
You have a right-angled triangle with hypotenuse of 400

the horizontal distance will be the x of that triangle
cos20° = x/400
x = 400cos20°

the vertical height will be the y of that triangle
.....
.....

I am sure you can take over from here
Answer to the question
Cos adj =cos20°×400. =Cos20° = 400. X cos 20° =. 400.
Cos 20°. Cos 20
X = 400
0•9397
400
0•9397= 425•7
