You make use of the relationships between angles in a circle, and the relationships between angles in a triangle. You are expected to know or have ready reference to the necessary relationships.

Upper Left.
.. x is the base angle of an isosceles triangle whose apex angle is twice 63°.
.. x = 27°

Upper Right.
.. x is supplementary to 73°.
.. x = 107°

Lower Left.
.. x is complementary to 50°.
.. x = 40°

Lower Right.
.. x is supplementary to twice the angle partially shown at the right side of the image. (The central angle between the radii to the tangent points is twice the angle partially shown. The angle to the radius at each point of tangency is 90°, and the sum of the 4 angles in the quadrilateral is 360°. Hence the relationship described in the first sentence.)

At 8:00 a.m., there were t inches of snow on the ground. At 5:00 p.m., there were 3t inches of snow on the ground. How many more
Anastaziya [24]

we conclude that at 5:00 p.m. there are 8 more inches of snow than at 8:00 a.m.

<h3>How many more inches of snow were on the ground at 5:00 p.m. than at 8:00 a.m.?</h3>

We know that at 8:00 a.m. there were t inches of snow in the ground.

At 5:00 p.m. there were 3t inches of snow in the ground.

Then the difference between the heights of the snow is:

3t- t = 2t

And we know that at 5:00 p.m. there were 12 inches of snow then we can solve the linear equation for t:

3t = 12in

t = (12in)/3 = 4 in

Replacing that in the difference of heights:

2t = 2*4in = 8in

From this, we conclude that at 5:00 p.m. there are 8 more inches of snow than at 8:00 a.m.
