Mathematics
1 answer:
rewona [7]3 years ago
4 0

Answer:

DR = 10 units

AR = 8.66 units

Step-by-step explanation:

By applying sine rule in the given right triangle,

sin(∠R) = \frac{\text{Opposite side}}{\text{Hypotenuse}}

sin(30°) = \frac{AD}{DR}

\frac{1}{2}=\frac{5}{DR}

DR = 10 units

By applying tangent rule in the given triangle,

tan(∠R) = \frac{\text{Adjacent side}}{\text{Hypotenuse}}

tan(30^0)=\frac{AD}{AR}

\frac{1}{\sqrt{3}}=\frac{5}{AR}

AR = 5√3

AR = 8.66 units
