Answer:

solution,

Let <DEF= x°

<CDE= 2x°

<BAF= 90°

The sum of interior angle of hexagon= 720°

<A + <B + <C + <D + <E +<F = 720°

$90 + 145 + 115 + 2x + x + 160 = 720 \\ 510 + 3x = 720 \\3x + 510 = 720 \\ 3x + 510 - 510 = 720 - 510 \\ 3x = 210 \\ \frac{3x}{x} = \frac{210}{3} \\ x = 70 \: degree$

Again,

$< \: cde = 2x \\ \: \: \: \: \: \: \: \: \: \: \: \: = 2 \times 70 \\ \: \: \: \: \: \: \: \: \: \: \: \: = 140 \: degree$

Hope this helps...

Good luck on your assignment..

I need help with numbers 1-4 please if someone could help me

laila [671]

You can use the slope formula or just calculate
$\frac{rise}{run}$
So for the first problem you run 3 units right and rise 5 units so
$\frac{rise}{run} = \frac{5}{3}$
2. Notice the y axis goes by 2 units.
$\frac{ - 10}{4} = \frac{ - 5}{4}$
3.
$\frac{0}{12} = 0$
4.
$\frac{2}{0} = undefined$
Please let me know if you have questions

One fabric cost $15.00 for 2 yards. Another cost $37.50 for 5 yards. Do both yards cost the same? Explain.

omeli [17]

Answer:

Yes.

Step-by-step explanation:

Both yards do cost the same.

$15.00 divided by 2 is equal to 7.5.

$37.50 divided by 5 is equal to 7.5.

Therefore, both yards cost the same.

Answer:

Sound can travel 12 miles per minute.

Step-by-step explanation:

Speed equation is distance divided by time.

So we have 1 mile per 1/12 of a minute.

Let’s write the equation.

Speed of sound = 1 / 1/12

Multiply by the reciprocal.

1 * 12 = 12.
