Question

Find the exact values of the indicated trigonometric functions. Write fractions in lowest terms.

Right triangle ACB is shown where segment AC is twenty one units, segment CB is seventy two units, and segment BA is seventy five units.

Find sin B and tan B.

Answer 1

sinB = 21/75

tanB = 21/22

Explanation:

sinΦ = Height / Hypotenuse

tanΦ = Height / Base

Answer 2

sin B = 7/25, tan B = 7/24

Explanation:

sin = opposite / hypotenuse, tan = opposite / adjacent

Maybe I missed something but all I did was recreate your triangle and solve the trig ratios.
