Answer:
X = -1, 3
Step-by-step explanation:
Answer:
a. Area = 1.94m²
b. Area = (p² + 0.5)m²
c. Height = 1.5m
Step-by-step explanation:
Given
<em>Let H represents Height and A represents Area</em>
<em>From the first and second statements, we have that:</em>
<em></em>
<em></em>
<em></em>
<em>a. Calculating Area When Height = 1.2</em>
<em></em>
<em></em>
<em>Substitute 1.2 for H</em>
<em></em>
<em></em>
<em></em>
<em></em>
<em></em>
<em></em>
<em></em>
Hence, the area is 1.94m²
<em></em>
<em>b. Calculating Area When Height = p</em>
<em></em>
<em></em>
<em>Substitute p for H</em>
<em></em>
<em></em>
<em></em>
Hence, the area is (p² + 0.5)m²
<em></em>
c. <em>Calculating Height When Area = 2.75m</em>²
<em></em>
<em></em>
<em>Substitute 2.75 for A</em>
<em></em>
<em></em>
<em>Subtract 0.5 from both sides</em>
<em></em>
<em></em>
<em></em>
<em></em>
<em></em>
<em></em>
<em></em>
<em>Take Square Root of both sides</em>
<em></em>
<em></em>
<em></em>
<em></em>
<em></em>
<em></em>
<em></em>
<em></em>
<em></em>
Hence, the height is 1.5m
Side adjacent to the given angle: x
Diagonal=hypotenuse=20
cos (36° 42') =(side adjacent to angle 36° 42')/Hypotenuse
cos (36° 42')=x/20
Solving for x. Multiplying both sides of the equation by 20:
20 cos (36° 42')=20 (x/20)
20 cos (36° 42')=x
x=20 cos (36° 42')
x=20 (0.801775644)
x=16.03551288
x=16.04
Answer: Option D. 16.04
