<span>Using trigonometry formula: sin a = cos (90 - a)
</span>cos (2x + 8) = sin (x + 37)
cos (90 - x - 37) = cos (53 - x)
Property of cosine function: (<span>2x + 8) = ± <span>(53 - x<span>)
2x + 8 = 53 - x
3x = 45
x = 15°
2x + 8 = -53 + x
x = -61°
Answer: x = 15°, x = -61°</span></span></span>
Answer:
The dimensions of the park on the scale drawing are 12 inches by 20 inches
The actual dimensions are given as:
Park = 600 feet by 1000 feet
Swing set = 25 feet by 100 feet
The dimension of the swing set on the scale drawing is given as: 0.5 inch by 2 inches
The above means that, the scale factor (k) is:
--- i.e. divide the scale measurement by the actual measurement
Evaluate both equations
So, we have:
Multiply the scale factor by the dimensions of the park, to get the scale measurement
Hence, the dimensions of the park on the scale drawing are 12 inches by 20 inches

Answer:Total money they will spend =$147,000
Step-by-step explanation:
Cost of 7 compact cars at $8,500 each
=$8,500 x 7 =$59,500
Cost of 7 midsize cars at $12,500 each
= $12,500 x 7 =$87,500
Total money they will spend =$59,500 +$87,500=$147,000
