Answer:

I believe you add, degrees in triangles are 180 so 80+65= 145. 180-145 is 35

Answer:

x=35

Step-by-step explanation:

you are going to want to subtract. the best thing about triangle angles is that they all add to equal 180º no matter what. so what you can do is subtract the given angles from 180. so 180-80-65. which gives us 35.

Hope this helps!

The price of a set of feeding bowls for dogs have been $9.25 , but was increased to $11.10. What was the precent increased

maw [93]

Answer:

As per the given statement:

Original price of a set of feeding bowls for dogs = $9.25

Increased Price = $11.10

To find the percentage increase.

$\text{Percentage increase} = \frac{\text{Increased Price}}{\text{Original Price}} \times 100$

Substitute the given values we have;

$\text{Percentage increased} = \frac{11.10}{9.25} \times 100$

Simplify:

$\text{Percentage increased} = 120\%$

therefore, the increased percentage was 120%
