Find the measures of the interior
Ainat [17]

Answer:

Angle 1 =  108°

Angle 2 =  72°

Angle 3 =  120°

Angle 4 =  96°

Angle 5 =  144°

Step-by-step explanation:

We need to find the measures of the interior  angles in a pentagon if the measure  of each consecutive angle is in the  ratio 9:6:10:8:12.

Let x be the common ratio

So, we can write:

Angle 1 = 9x

Angle 2 = 6x

Angle 3 = 10x

Angle 4 = 8x

Angle 5 = 12x

We know that the <em>sum of all angles of pentagon = 540</em>

So, adding all angles and equal them to 540, we can find value of x

9x+6x+10x+8x+12x=540\\45x=540\\x=\frac{540}{45}\\x=12

So, we get the value of x: x=12

Now, calculating the angles by putting x=12:

Angle 1 = 9x = 9(12) = 108°

Angle 2 = 6x = 6(12) = 72°

Angle 3 = 10x = 10(12) = 120°

Angle 4 = 8x = 8(12) = 96°

Angle 5 = 12x= 12(12) = 144°

Solve the equation . (-2 1/7)p=-3
34kurt

Answer:

p = \frac{7}{5}

Step-by-step explanation:

change the mixed number to an improper fraction

- 2 \frac{1}{7} = - \frac{15}{7}, hence

- \frac{15}{7} p = - 3 ( multiply both sides by 7 )

- 15p = - 21 ( divide both sides by - 15 )

p = \frac{-21}{-15} = \frac{7}{5}
