Answer:
see explanation
Step-by-step explanation:
Given
tan a =
= 
We require the hypotenuse h
Using Pythagoras' identity
h² = 9² + 40² = 81 + 1600 = 1681 ( take square root of both sides )
h =
= 41 , thus
sin a =
= 
cos a =
= 
Step-by-step explanation:
Area of square =side×side
=12×12
=144cm^2
Hope this helped! :)
I think the equation is y= -1/3x+1. The slope is going down, so it’s negative. And the y intercept is 1. And how I got a fraction is by using rise/run.
