Answer:
<em>1st triangle:</em>
sin(C): 0.64,
cos(C): 0.8,
<em>Second triangle:</em>
sin(C): 0.75,
cos(C): 0.67,
Step-by-step explanation:
Using SOH CAH TOA, we know that to find the sin of an angle, it's Opposite/Hypotenuse.
To find the cos of an angle, it's adjacent/hypotenuse.
<u>In the 1st triangle:</u>
The adjacent to C is 16, the hypotenuse is 25.
is the sin of C.
The adjacent to C is 20, and the hypotenuse is 25.
is the cos of C.
<u>In the second triangle:</u>
The opposite to C is and the hypotenuse is 2.
is the sin of C.
The adjacent to C is 2 and the hypotenuse is 3.
is the cos of C.
