Geometry math question please help
stiks02 [169]

You need this key result: in any polygon, the sum of the interior angles is

(n-2)\times 180

where n is the number of sides of the polygon.

Your polygon has seven sides, and the measures of all angles are given. So, we can write

2x+4x+4x+4x+4x+2x+10x = (7-2)\times 180

Again, we've simply written that the sum of all interior angles is the number of sides, minus two, times 180.

We can simplify both sides: we sum like terms on the left hand side, and we easily compute the right hand side:

30x = 5\times 180 = 900

and we can solve this equation for x by dividing both sides by 30:

x = \cfrac{900}{30} = 30

Finally, the required angles is 2x = 2\times 30 = 60

Donnie's dog had a litter of puppies. He notices that 2 are brown, 1 is white, and 3 are spotted. What is the ratio of total pup
Levart [38]

Answer:

The ratio of total puppies to brown puppies is 3 for 1. For every 3 puppies there is 1 brown puppie.

Step-by-step explanation:

In order to find the ratio between the total puppies to brown puppies we need to take the total amount of puppies , that is, the sum of all the puppies and divide it by the number of brown puppies. So we have:

ratio  = total amount of puppies/brown puppies

ratio  = (3+2+1)/(2) = 6/2 = 3/1

The ratio is for every three puppies we have one brown puppie.

What is the measure of NRS?
never [62]

Answer:

<h3>C. 113°</h3>

Step-by-step explanation:

(7x - 1) + 79° = 21x + 8

• An exterior angle of a triangle is equal to the sum of its two interior opposite angles.

(7x - 1) +79  = 21x + 8 \\ 7x - 1 + 79 = 21x + 8 \\ 7x +  78 = 21x + 8 \\ 78 - 8 = 21x - 7x \\ 70 = 14x \\  \frac{70}{14}  = x \\ 5 = x \\

NRS = 21x + 8

21x + 8 \\ 21(5) + 8 \\ 105 + 8 \\  {113}^{o}
