In any right triangle ABC, with right angle A we have the following:

\sin(\angle B)=\cos(\angle C)

and

\sin(\angle C)=\cos(\angle B).


This means that the sine of a non 90° angle, is equal to the cosine of its complementary angle.


Thus, \displaystyle{ \cos(\angle M)=\sin (\angle L)= \frac{19}{20}.


(Take a look at the picture. From the definition of trigonometric ratios in right triangles we have :
\displaystyle { \sin(\angle L)= \frac{opposite \ side}{hypotenuse} = \frac{19}{20}.
and
 \displaystyle { \cos(\angle M)= \frac{adjacent \ side}{hypotenuse} = \frac{19}{20}.)

Answer: 19/20

Please explain how you would prove that all circles are similar?
NISA [10]

Answer:

Shapes are similar when one can be scaled to be like another one. Circles are always the same shape and they only vary in size. A very small circle can be expanded to be the same size as any other without changing it's shape, only size. However this is not true for ovals since they come in different shapes.

Anna [14]

Answer:

56.3 cm

Step-by-step explanation:

\dfrac{\sin 28^\circ}{27} = \dfrac{\sin 102^\circ}{c}

c\sin 28^\circ = 27 \sin 102^\circ

c = \dfrac{27 \sin 102^\circ}{\sin 28^\circ}

c = 56.3
