Answer:

m∠A = 144°, m∠B = 36°

Step-by-step explanation:

Supplementary angles are angles that add up to 180 degrees.

Substitute 4(m∠B) for m∠A.

4(m∠B) + m∠B = 180

5(m∠B) = 180

<u>m∠B = 36°</u>

Substitute 36 for m∠B.

4(36) = m∠A

<u>m∠A = 144°</u>

A town has three roads that form an obtuse triangle. James wants to set up a refreshment stand so that the shortest distance fro
GarryVolchara [31]
He should set up the refreshment stand on the incenter of the obtuse triangle. The incenter of a triangle is described as the intersection between the angle bisectors of a triangle. The inradius are the line segments from the incenter of the triangle to each of the three sides of the triangle which are all equal. The inradius is depicted as the radius of an inscribed circle in the triangle. Therefore, the shortest equal distance from his stand to each road is C. on the incenter.

13 + 11s = -15 + 8s − 20
koban [17]

<em>Answer,</em>

<em><u>S = -16</u></em>

<em>Explanation,</em>

<em><u>Step 1: Simplify both sides of the equation.</u></em>

<em>13 + 11s = − 15 + 8s − 20</em>

<em>13 + 11s = − 15 + 8s + − 20</em>

<em>11s + 13 = (8s) + (</em><em><u>− 15</u></em><em> + </em><em><u>− 20</u></em><em>) </em><em>(Combine Like Terms)</em>

<em>11s + 13 = 8s + − 35</em>

<em>11s + 13 = 8s − 35</em>

<em><u>Step 2: Subtract 8s from both sides.</u></em>

<em>11s + 13 − 8s = 8s − 35 − 8s</em>

<em>3s + 13 = − 35</em>

<em>Step 3: Subtract 13 from both sides.</em>

<em>3s + 13 − 13 = − 35 − 13</em>

<em>3s = − 48</em>

<em><u>Step 4: Divide both sides by 3.</u></em>

<em>3s/3 = −48/3</em>

<em>s = -16</em>


<u><em>Hope this helps :-)</em></u>

Help me answer this please!!! i will mark you brainliest
goldfiish [28.3K]

Answer:

363 ft.

Step-by-step explanation:

To calculate the base side which is b we use the trigonometric identity called cosine.

cos \theta=\frac{base}{hypotenuse} \\\\cos25 = \frac{b}{400}\\\\b=400*cos 25\\b=400*0.906\\b=362.5\ ft

Since we the answer to the nearest whole number it would be b = 363 ft.

What is the slope intercept form of -1/2 and 1, -1/2 being the slope??
nevsk [136]
The slope-intercept form of the equation of a straight line is y=mx+b, where m is the slope and b is the y-coordinate of the y-intercept.

If the given slope is -1/2, then this equation becomes y = (-1/2)x + b.

You do not say that b=1.

But if we let b=1, then the equation becomes y = (-1/2)x + 1.

What does P equal -3(2+4p)=2(2p-1)
Whitepunk [10]
P=-1/4

Work:
-3(2+4p)=2(2p-1) distributive property space now it’s -6-12p=4p-2
-6-12p=-4p-2 add 4p on both sides
-6-16p=-2 add 6 on both sides
-16p=4 divide both sides by -16
P=-1/4
