Step-by-step explanation:
basically solving for arccos(8.5/9.9) in degrees, had to run through calculator
Answer:
You can use Gaussian Elimination.
Double both sides of the first equation and add the second equation.
6x + 4y = 8
5x - 4y = 3
---------------
11x = 11
x = 1
5 - 4y = 3
-4y = -2
y = 1/2
Step-by-step explanation:
The area of real backyard is 72 square meters.
Step-by-step explanation:
Given,
Length of rectangular backyard = 8 cm
Width of rectangular backyard = 4 cm
According to scale;
2 cm = 3 m
1 cm = 
Real length of backyard = 8*1.5 = 12 m
Real width of backyard = 4*1.5 = 6 m
Real area of backyard = Length * Width
Real area of backyard = 12*6 = 72m²
The area of real backyard is 72 square meters.
