Answer:

5.13 feet

Step-by-step explanation:

So, we have the full dimensions of flag #1, and we have the partial dimensions of flag #2, which should follow the same ratio as flag #1, since not indicated otherwise.

When you need to compare dimensions like that, the easiest way to proceed is to do a cross-multiplication. Let's say x is the length of flag #2 we're looking for.  It's ratio over the width of flag #2 will be the same as the ratio of the length of flag #1 over its width, so:

\frac{x}{2.7} = \frac{1.9}{1}

If we isolate x, we have x = (2.7 * 1.9) / 1 = 5.13 feet

Which makes sense since we know the result should be a bit less than 2.7 times 2.

In the diagram shown at left, three lines intersect to form a triangle.<br> What is the value of x?
Phoenix [80]

Answer:

39°

Step-by-step explanation:

For a straight line, the sum of angle is 180°

At the point where we have the 107°, the inner angle in the triangle will be 180-107=73°

68° is alternate angle to the inner angle in the triangle

Since the sum of angles in a triangle are 180°, then angle x will be

X=180-73-68=39°

Therefore, missing angle is 39°

Estimate the quotient 63.5 divided by 5
skad [1K]
Dividing by 5 is equivalent to dividing by 10 and then multiplying by 2.
therefore:

63.5/5 = (63.5/10) * 2 = 6.35 * 2 =12.70 which rounds to 13.
