Answer:

4/3

Step-by-step explanation:

  • multiply (top) numerator x numerator and (bottom) denominator x denominator
  • 2 x 10 = 20  and 5 x 3 = 15  or 20/15
  • So, 2/5 x 10/3 = 20/15
  • reduce 20/15 to simplest terms, both are divisible by 5
  • divide both numerator and denominator by 5 and get:
  • 20/15 = 4/3
  • So, 2/5 x 10/3 = 4/3

How to find the θ in this equation: tan(θ+16°)=1/tan(θ+60°) by using the trigonometric identities?thanks
DedPeter [7]

Answer:

\huge \theta  =7°

Step-by-step explanation:

tan( \theta + 16 \degree) =  \frac{1}{tan( \theta + 60 \degree) }  \\ tan( \theta + 16 \degree) =cot( \theta + 60 \degree) \\ tan( \theta + 16 \degree) = tan \{90 \degree - (\theta + 60\degree) \} \\ \theta + 16 \degree = 90 \degree - \theta  -  60\degree \\ \theta +\theta  = 30 \degree - 16\degree \\2 \theta  = 14 \degree  \\ \theta  =  \frac{14 \degree}{2}   \\   \huge \red{ \boxed{\theta  =7 \degree}}
