Answer:
A) The table shows a proportional relationship (as the number of pages increase the time is proportionally increasing as well)
D) The 11th page of notes takes longer than normal (too long time duration) o((⊙﹏⊙))o.
Answer:
.
Step-by-step explanation:
Assume that the run of this rafter is level. Then the height of the ridge (the line with a question mark next to it in the diagram) should be perpendicular to the line marked with 
. The three labelled lines in this diagram will form a right triangle.
- The line marked as
will be the hypotenuse of this right triangle. - The line marked as
will be one of the triangle's legs. - The line representing the height of the ridge (the one with the question mark) will be the other leg of this right triangle.
Hence, the height of this ridge can be found with the Pythagorean Theorem. By the Pythagorean Theorem:
.
In this particular right triangle:
.
.
Therefore, the height of this ridge would be 
. (Note the unit.)
Answer:
x = (-9)
Step-by-step explanation:
From the diagram, we see that the triangle is an isosceles triangle. Since it is an isosceles triangle we know that the angles at the base of an isosceles triangle are equal to each other, so the angles that is not marked will be equal to m∠2. Since now we know that, we can make the following equation...
m∠2 + m∠2 + 84 = 180
Now we solve it and get...
2(m∠2) = 180 - 84
2(m∠2) = 96
m∠2 = 48
Now we substitute m∠2 with x + 57, and get...
m∠2 = 48
x + 57 = 48
x = 48 - 57
x = (-9)
