How to find this answer using sine or cosine law?

SashulF [63]

We know that According to Law of Sines :

$\frac{SinA}{a} = \frac{SinB}{b} = \frac{SinC}{c}$

where A - B - C are the Angles of the Three Vertices of the Triangle

a - b - c are the lengths of the Opposite sides of the Angles of the Respective Vertices A - B - C

From the Given Triangle we Can Notice that :

$\frac{SinC}{28} = \frac{Sin92}{41}$

$SinC = \frac{0.999\times28}{41}$

$SinC = \frac{27.98}{41}$

SinC = 0.682

$C = \sin^-^1(0.682)$

C = 43°

valentina_108 [34]

Answer:

45 %

Step-by-step explanation:

Time left until Christmas = 2 weeks

= 2 * 7 days [since 1 week = 7 days]

= 14 days

Number of days in December = 31

Percentage of the month left before Christmas = $\frac{Time left until Christmas}{Number of days in December} * 100$

= $\frac{14}{31} * 100$

= 0.45 * 100

= 45 %

PLEASE HELP IF YOU SEE THIS. I really need help.How do you write an equation of a line given 2 points? Write the equation for th

Pani-rosa [81]

Answer:

The answer of your question is: y = - x + 11

Step-by-step explanation:

Data

A (3, 8)

B (9,2)

Formula

m = $\frac{(y2 - y1)}{(x2 - x1)}$

(y - y1) = m(x - x1)

Process

1.- Calculate the slope

m = $\frac{2- 8}{9 -3}$

= $\frac{-6}{6}$

m = -1 slope

2.- Substite point A and slope in the equation

(y - 2) = - 1(x - 9)

y - 2 = -x + 9

y = -x + 9 + 2

y = - x + 11 Solve for y
