Answer 2

Answer:

Length of TR= 21 unit

$\cot(m) = \frac{20}{21}$

$\sec(r) = \frac{29}{21}$

Step-by-step explanation:

$\sin(r) = \frac{20}{29} = \frac{p}{h}$

On the above Diagram

p=MT=20

h=MR=29

b=TR

$= \sqrt{ {h}^{2} - {p}^{2} }$

$\sqrt{ {29}^{2} - {20}^{2} } = \sqrt{841 - 400} = \sqrt{441} = 21$

Sec R

$= \frac{h}{b} = \frac{29}{21}$

To Find Cot M

Exchange the position of M and R

Now

b=TM=20

p=TR=21

h=MR=29

Cot M=b/p=20/21
