son4ous [18]

Answer:

x = 4

y = 2

Step-by-step explanation:

x - y = 2

x = 2 + y

2x + 3y = 14

2(2 + y) + 3y = 14

4 + 2y + 3y = 14

4 + 5y = 14

5y = 10

y = 2

x - y = 2

x - 2 = 2

x = 4

Problem 9
By definition,
$tan 22^{o} = \frac{203}{x} \\ 0.404 = \frac{203}{x} \\ x = \frac{203}{0.404}= 502.44$

Answer: 502.4 m

Problem 10
From geometry, the angle opposite x is 27°.
By definition,
$sin 27^{o} = \frac{x}{580} \\ 0.454 = \frac{x}{580} \\ x=(580)(0.454)=263.32
$
