What is the sum of the interior angles of the polygon shown below

Ipatiy [6.2K]

Answer:

900

Step-by-step explanation:

The sum of the interior angles of a polygon with n sides is given by the formula:

$S=(n-2)180$

The polygon given has 7 sides. Substitute 7 for n. Thus:

$S=(7-2)180\\S=5(180)\\S=900$

The sum of the interior angles is 900 degrees.

Write the ratios for sin A and cos B. The triangle is not drawn to scale.

babymother [125]

By definition we have:
sineA = (C.O) / (h)
cosA = (C.A) / (h)
Where,
C.O: opposite leg
C.A: adjacent leg
h: hypotenuse
Substituting values:
sinA = (48) / (50)
cosA = (14) / (50)
Answer:
sineA = (48) / (50)
cosA = (14) / (50)
