Answer:
<u>Find the slope:</u>
<u>Use point-slope form and one of the points:</u>
- y - y₁ = m(x - x₁)

Answer:

Step-by-step explanation:
Remember that the equation of the line is

in this case we have

that is because

Expenditures are negatives do I'd use -42.50
Answer:
100
Step-by-step explanation:
Isosceles triangle have 2 equal angles. Therefore the second angle in the triangle will also be 25.
Since the sum of angles in a triangle is 180.
180-(25x2) will give you the last angle in one of the triangles.
The other angle is identical so the angle at the top of the other triangle will also be 130.
The sum of angles in a circle is 360.
Therefore, angle x = 360-(130x2)
X= 100
Medida do angulo central = medida do arco interceptado
arco = 25º e ângulo central = 25º
