Kindly check explanation
Step-by-step explanation:
Since the triangle is right angled ; we can solve for x using Pythagoras :
x = hypotenus ; hence ;
x² = opposite² + adjacent²
x² = 15² + 8²
x² = 225 + 64
x² = 289
x = √289
x = 17
Using Trigonometry :
Sin D = side opposite D / hypotenus = 8/17
Cos D = side Adjacent D / hypotenus = 15 / 17
Tan D = side opposite D / Adjacent side = 8/15
Sin F = side opposite F / hypotenus = 15/17
Cos F = side Adjacent F / hypotenus = 8 / 17
Tan F = side opposite F / Adjacent side = 15/8

Answer:
Let's solve your equation step-by-step.
|−x−15|=|5x−23|
Solve Absolute Value.
|−x−15|=|5x−23|
We know either−x−15=5x−23or−x−15=−(5x−23)
−x−15=5x−23(Possibility 1)
−x−15−5x=5x−23−5x(Subtract 5x from both sides)
−6x−15=−23
−6x−15+15=−23+15(Add 15 to both sides)
−6x=−8
−6x

−6
(Divide both sides by -6)
x=

−x−15=−(5x−23)(Possibility 2)
−x−15=−5x+23(Simplify both sides of the equation)
−x−15+5x=−5x+23+5x(Add 5x to both sides)
4x−15=23
4x−15+15=23+15(Add 15 to both sides)
4x=38

The answer is inches
Step 1. Subtract length of the door from the width of the door:
Step 2. You want the same space to be on each side of the bar. So, divide the difference from step 1 by 2:
