Answer:

$Area = 112.1 m^2$

Step-by-step Explanation:

Given:

∆WXY

m < X = 130°

WY = x = 31 mm

m < Y = 26°

Required:

Area of ∆WXY

Solution:

Find the length of XY using Law of Sines

$\frac{w}{sin(W)} = \frac{x}{sin(X)}$

X = 130°

x = WY = 31 mm

W = 180 - (130 + 26) = 24°

w = XY = ?

$\frac{w}{sin(24)} = \frac{31}{sin(130)}$

Multiply both sides by sin(24) to solve for x

$\frac{w}{sin(24)}*sin(24) = \frac{31}{sin(130)}*sin(24)$

$w = \frac{31*sin(24)}{sin(130)}$

$w = 16.5 mm$ (approximated)

$XY = w = 16.5 mm$

Find the area of ∆WXY

$area = \frac{1}{2}*w*x*sin(Y)$

$= \frac{1}{2}*16.5*31*sin(26)$

$= \frac{16.5*31*sin(26)}{2}$

$Area = 112.1 m^2$ (to nearest tenth).

Answer:

-5/8 + 6/8= 1/8

6/8 is the same thing as 3/4 btw so don't get confused.

Salsk061 [2.6K]

Answer:

4 + 5x = 3 (-x + 3) -11

4+5x=-3x+9-11

5x+3x=9-11-4

8x= -6

x= -0.75

38b/-19<br><br> please help me

Natasha2012 [34]

You didn't write what to do with the fraction but I think you meant to ask to simplify it:
38b/-19
Multiply - 19 from top and bottom :
-2b
