In the given image, first black line is drawn.
Then an arc with green color is draw on the black line.
Then by same width of the compass draw another arc above.
And cut the green arc by same angle on the black line.
And then draw a yellow line.
We can see those are corresponding angles equal.
So, the lines would be parallel.
<h3>So, correct option is : D. Parallel lines.</h3>
⇒ Solutions
<span>To solve the given problem you first have to plug all the numbers in....
324 m</span>²<span> is the SA so 324 m</span>²<span> = 2[(5m </span>× <span>12m) + (5m </span>× <span>h) + (12m </span>× <span>h)]
You want to find the variable h so first start by dividing 342 by 2 which will make your equation simpler to solve.
= 162 m</span>²<span> = (5m </span>× <span>12m) + (5m </span>× <span>h) + (12m </span>× <span>h)
Multiply your "lw" together 5m </span>× <span>12m = 60m</span>²<span> and you have
162 m</span>² <span>= 60 m</span>²<span> + (5m </span>× <span>h) + (12m </span>× <span>h)
You can subtract 162 m</span>²<span> by 60 m</span>²<span> leaving 102 m</span>²<span> = (5m </span>× <span>h) + (12m </span>× <span>h)
Then combine your like terms of h....5m </span>× <span>h + 12m </span>× <span>h = 17m </span>× <span>h so you now have
102m</span>²<span> = 17m </span>× <span>h and to get (h) by itself to solve for it you can then divide by 17 leaving 6m = (h) making your height equal 6 meters.

(SA/2 - lw) = (h(l+w) ...... Subtract terms not containing (h)
(SA/2 - lw) ÷ <span>(l+w) = (h) ..... Divide by the coefficient of (h) </span>
(324/2 - 5 × 12) ÷ <span>(5+12) = (h) ... Plug in the numbers

(162 - 60) ÷ <span>17 = (h) = 6 ... Answer </span>
The correct answer to your question is number 2
A the other ones really don’t make sense
Answer:
70 decreases each stage
Step-by-step explanation:
350 / 5 = 70 decreases each stage
Since all decreases are equal and in 5 stages:
decreases * stages = total decreases
70 * 5 = 350
