Answer: the length of the angle bisector of angle ∠A is 6 ft
Step-by-step explanation:
The diagram of the right angle triangle ABC is shown in the attached photo
Looking at triangle ABC,
cos θ = adjacent side/hypotenuse side
cos θ = 5/13 = 0.3846
θ = 67.38 degrees
The bisector of an angle divides it into two equal halves. The bisector is represented by line AD.
θ/2 = 67.38/2 = 33.69 degrees
Therefore,
Cos 33.69 = 5/AD
AD × Cos 33.69 = 5
AD = 5/Cos 33.69 = 5/0.832
AD = 6 ft

I'm here! This Problem is easy :) The answer is 4
Step-by-step explanation:
2x+10=5x−2
<em>Subtract </em>5x from both sides
2x+10−5x=−2
<em>Combine</em> 2x and −5x to get −3x.
−3x+10=−2
Subtract 10 from <em>both sides.</em>
−3x=−12
<em>Divide</em> both sides by −3.
Divide −12 by −3 to get 4.
x = 4 (D)
