The answer is what that guys said
(Also what grade is this?)
The first angle is 76 and the second angle is 14. You can check this by doing 14+5=19 and then multiply that by 4.
Answer:
588 sq. in.
Step-by-step explanation:
The total volume of air inside the skylight is in the shape of a pyramid, not the rectangular prism at the bottom.
So, if we look at the pyramid, it has a square base with dimensions 14 x 14. Its height is 11 - 2 = 9.
Formula for volume of a pyramid is:
V = 1/3 * Area of Base * height
Area of Base (since it is a square) = 14 * 14 = 196
Height is 9
<em>plugging into the formula, we get:</em>
<em>
</em>
<em />
<em>Hence, volume is 588 sq. in.</em>
the given figure is a rhombus, so it's area =

where, d1 and d2 are diagonals of the rhombus,
and since, the diagnonals of rhombus bisects each other, the values of their diagonals are
(2 × x) and (2 × 15) =》2x and 30 respectively,
so, by finding the area using the given diagonals and equating it with the real area, we get :
=》

=》

=》

=》

so,
value of x = 10 units
Answer:
C)
Step-by-step explanation:
The one with the line that has a steep positive slope. (The slope is the x-coefficient, 3.5. This means the line goes up 3.5 units for each unit it goes to the right.)
