Answer:
cos x = 4/5
cos y= 3/5
tan y= 4/3
Step-by-step explanation:
Sinx=3/5
Meaning opposite to x / hypotenuse is 3/5.
The height of the triangle is 3 and the hypotenuse is 5.
Use pythagorean theorem to find the base value of the triangle.
Base is 4.
cos x = 4/5
cos y= 3/5
tan y= 4/3
TIP:
S O/H
C A/H
T O/A
This is a fun word play that helps remember all trig functions.
S= Sine
C= Cosine
T= Tangent
O= Opposite
H= Hypotenuse
A= Adjacent
