Point slope form is written in [ y - y1 = m(x - x1) ]

The only option that is written this way is Option C.

(y - 3) = -4(x + 8) where m = -4, y1 = 3, and x1 = -8.

Best of Luck!

Answer:

x=37

Step-by-step explanation:

You know all the angles in a triangle add up to 180.

Therefore, you add 72° and 71° which equals 143.

Then you subtract 180 and 143 which equals 36.

[72+71=143

180-143=37]

I hope this helps you!

How many sides does a polygon have if the sum of the measure will of the interior is 10260

Klio2033 [76]

The polygon have 59 sides.

Solution:

Sum of the measure of interior angle of the polygon = 10260°

Interior angle theorem of polygon,

<em>The sum of measure of interior angles of a polygon is (n – 2) × 180°.</em>

By this theorem,

(n – 2) × 180° = 10260°

Divide by 180° on both sides.

$$\frac{(n - 2) \times 180^\circ}{180^\circ} = \frac{10260^\circ}{180^\circ}$

$n-2=57$

Add 2 on both sides, we get

n – 2 + 2 = 57 + 2

n = 59

Hence the polygon have 59 sides.

James hiked on two trails. The first trail was l 2/5 miles long, and the second trail was 5 times as long as the first trail. Ho

Licemer1 [7]

Answer:

$6 \frac{2}{5} \: miles$

Step-by-step explanation:

$First \: trail = 1 \frac{2}{5} = \frac{7}{5} \: miles \\ \\ second \: trail = 5 \times first \: trail \\ \\ = 5 \times \frac{7}{5} \\ \\ = 7 \: miles \\ \\ total \: length = \frac{7}{5} + 5 \\ \\ = \frac{7 + 25}{5} \\ \\ = \frac{32}{5} \\ \\ = 6 \frac{2}{5} \: miles$
