Answer:

x = 14

Step-by-step explanation:

110 + 5x = 180

-110 -110

5x = 70

divide by 5 on both sides

x = 14

to find y add 70 + 40 + missing angle = 2y

missing angle is 70 because 70+40+70 = 180

so 2y = 110

y = 55

Use the basic proportion = -to solve the following problem for the unknown quantity. Round your answer to the

Digiron [165]

Answer:

154.34%

Step-by-step explanation:

We are asked to determine what percentage of 357 is 551.

Let us assume that x% of 357 is 551.

So, $\frac{357 \times x}{100} = 551$

⇒ $\frac{x}{100} = \frac{551}{357}$

⇒ $x = \frac{551}{357} \times 100$ ......... (1)

⇒ x = 154.34%

So, it is clear from the step (1) that when we take the basic ratio then multiply with 100, then we will get the percentage. (Answer)
