Answer:

x=70, which is D.

Step-by-step explanation:

As you can see, (2x-30) and x are different angles, but add up to 180. So, we can make an equation that looks like this:

(2x-30)+x=180

2x-30+x=180

3x=210

x=70

                                                     :)

Answer:

The answer is 18 cm

Step-by-step explanation:

<h3><u>Given</u>;</h3>
  • A force of 100 newtons stretches a spring 5 cm
<h3><u>To </u><u>Find</u>;</h3>
  • If a force of 360 newtons then how much a spring will be stretches

Now, We need to write a proportion

Here,

Force₁ = 100 N

Length₁ = 5 cm

Force₂ = 360 N

Length₂ = x cm

Now,

Force₁ ÷ Length₁ = Force₂ ÷ Length₂

100/5 = 360/x

100x = 360 × 5

100x/100 = 360 × 5/100

x = 18 cm

Thus, If a force of 360 newtons then 18 cm a spring will be stretches.
