How do you solve this problem
Kryger [21]

Answer:

sin(A) = \frac{21}{{29} }

cos(A)=\frac{20}{29 }

tan(A)=\frac{21}{20}

sin(C) = \frac{20}{{29} }

cos(C)=\frac{21}{29 }

tan(C)=\frac{20}{21}

Step-by-step explanation:

So first we need to make sure we know the trig identities to solve this problem.

  • sin(\alpha )=\frac{opposite}{hypotenuse}
  • cos(\alpha )=\frac{adjacent}{hypotenuse}
  • tan(\alpha )=\frac{opposite}{adjacent}

Here we only have two legs of the triangle, so we will need to use the Pythagorean Theorem a² + b² = c² to solve for the missing leg, the hypotenuse in this case.

  • Solving for the hypotenuse, c, we get c = \sqrt{a^{2} +b^{2} }
  • Here a = 20 and b = 21, so plugging in these values to the equation we get: c= \sqrt{(20)^{2}+(21)^{2}  } =\sqrt{400+441} =\sqrt{841}=29

Now we can use the trig identities to figure out the missing values for the problem

  • sin(A) = \frac{21}{{29} }
  • cos(A)=\frac{20}{29 }
  • tan(A)=\frac{21}{20}
  • sin(C) = \frac{20}{{29} }
  • cos(C)=\frac{21}{29 }
  • tan(C)=\frac{20}{21}
