Answer:
see explanation
Step-by-step explanation:
Using the cosine and tangent trigonometric ratios and the exact values
cos30° = and tan30° = , then
cos30° = = = ( cross- multiply )
× m = 12 ( divide both sides by )
m = ← rationalise by multiplying numerator/ denominator by )
m = × = = 4
-------------------------------------------------------------------------------
tan30° = = = ( cross- multiply )
× n = 6 ( divide both sides by )
n = ← rationalise the denominator
n = × = = 2

The area of △XYZ according to the figure is 363ft²
The formula for calculating the area of a triangle is expressed as:
A = 0.5bh
For the triangle △NMO
Area of △NMO = 0.5bh
147 = 0.5b(14/12)
147 = 7b/12
7b = 12 * 147
b = 252
b = 252ft
b = 3024in
Get the base of △XYZ
14/3024 = 22/XZ
XZ = 4,752in
Area of △XYZ = 0.5 (4,752)(22)
Area of △XYZ= 52,272in²
Area of △XYZ = 363ft²
Hence the area of △XYZ is 363ft²

y = (-2/3)x-3
Hello:
equation is the line is : y = ax+b a is a slope
y = (-2/3)x+b
passing through the point (−3;−1) : -1 =(-2/3)(-3)+b so : b = -3
second solution : you can verify (-3 ; -1) in the equation : y = (-2/3)x-3
512 i dont really know what you are asking for but the smallest number is 512 which also has a small value
