Sin theta = 9/15. Find tan theta. A. 15/12. B. 9/12 C. 12/15 D. 12/9

Finger [1]

Answer:

B

Step-by-step explanation:

$Sin \ theta = \frac{9}{15}=\frac{Opposite \ side}{hypotenuse}\\$

Pythagorean theorem,

Adjacent side ² = hypotenuse² - opposite side²

= 15² - 9²

= 225 - 81

= 144

Adjacent side = √144 = √(12*12) = 12

$Tan \ theta = \frac{opposite \ side}{adjacent \ side}= \frac{9}{12}$

It usually works well to do what the instructions tell you. Multiply each diameter by 3.14.

a) 3.14×6 cm = 18.84 cm

b) [can't read the picture]

d) 3.14×9 in = 28.26 in

e) 3.14×11 mm = 34.54 mm
