Call x and y those angles. If they are complementary, then their sum equals 90°:
x + y = 90°
y = 90° - x
The ratio of them is 5 to 1. So,
x/y = 5/1
x/(90° - x) = 5/1
x = 5 * (90° - x)
x = 450° - 5x
x + 5x = 450°
6x = 450°
x = 450°/6
x = 75°
The measure of the other angle is
y = 90° - 75°
y = 15°
The angles are 75° and 15°.
I hope it helps. =)

</span>We can use Galileo's square cube law to calculate the ratio between two similar pyramids. The law is used to describe the change of the area or the volume of the shape when their dimensions increase or decrease:

<span>
</span><span><span> <span> <span> <span> <span> <span> <span> <span> <span> <span> <span> </span></span></span></span></span></span></span></span></span> </span></span> </span>
V₁ and V₂ - volumes of pyramids,
l₁ and <span>l</span>₂ - the edges of pyramids.

Answer:
4 times 312 = 1,248 = 312 times 4 = 1,248
Hope this helps, sorry if it didn't.
<span>add 13.3 + (–7)
= 13.3 - 7 = 6.3
</span>Subtract.
<span>–56 – (–27.07)
</span>= -56 + <span>27.07
= -28.93
</span>simplify
<span>14- (-8)+5 -(-10)
</span>= 14 + 8 + 5 + 10
= 37
