Answer:

112 degrees

Step-by-step explanation:

Angle J and the other angle combines to form a straight angle. In other words, they must total 180 degrees. Thus:

68+j=180

Subtract 68 from both sides:

j=112\textdegree

And we're done!

From the setup of the problem, the "length of the top of the bookcase, measured along the attic ceiling" will be the hypotenuse of a right triangle, the length "AB". We have both the angle between AB and AC and the length of AC (3.24 meters), so we can use trigonometric identities.

The cosine of the 40 degree angle between AB and AC is equivalent to the length of AC divided by the length of AB. Equivalently, we have:

cos(40) = \frac{3.24}{h}

where "h", the hypotenuse, is the length we want. Rearranging the formula to solve for h we have that

$h = \frac{3.24}{cos(40)}$

which is 4.2295... meters. Converting to centimeters (multiplying by 100) we have that h = 422.95... centimeters, or if we round the value, h = 423 centimeters.

What is the distance between -13 and 13 on a number line
Ipatiy [6.2K]

Answer:

26 units

Step-by-step explanation:

Due to:

in the rect line, left to zero = 13 (absolute value)

in the rect line, right to zero = 13 (absolute value)

So the sum of each absolute value is the distance.

Best regards
