Answer:
m<ACD = 
Step-by-step explanation:
From the question given, ΔACD is a right angled triangle. Then we can apply one of the properties of a triangle to it.
In the triangle ACD:
<ACD + <DAC + <ADC = 180 (sum of angles in a triangle)
<ACD + 40 + 90 = 180
<ACD + 130 = 180
<ACD = 180 - 130
<ACD = 
With the application of the property of the sum of interior angles of a triangle, the measure of <ACD is
.
To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above:
- The<span> rectangular deck has the following dimensions: 12 ft by 14 ft.
- When the length and width are increased by the same amount, the area becomes 288 ft</span>².
2. Therefore, you have:
A=bxh
288=(12x)(14x)
288=168x²
3. When you clear the x, you obtain:
x=√288/168
x=(2√21)/7≈1.31
