Answer:
Step-by-step explanation:
X^2 = 73 - y^2
<span>x^2 - y^2 = 55 </span>
<span>substituting in to it </span>
<span>73 - 55 = 2y^2 </span>
<span>18 = 2y^2 </span>
<span>y = 3 </span>
<span>x^2 - 73 - 9 </span>
<span>x = 8 </span>
<span>answer is A</span>
Answer: I think its A
Step-by-step explanation: maybe
The length of the ladder that makes an angle of 75 degrees and lies against the wall of a house that's 23 feet tall is <em>approximately </em>25.88 feet.
The ladder forms a right triangle as it lies against the wall as shown in the image below.
<em><u>Thus:</u></em>
x = length of the ladder (hypothenuse)
Reference angle 
25 ft = Opposite
Apply SOH:
<em>Thus</em>,


Therefore, the length of the ladder that makes an angle of 75 degrees and lies against the wall of a house that's 23 feet tall is <em>approximately </em>25.88 feet.
