Question

Do number 4 and 5 please I don’t know how to do this. If your don’t know the formula for Pythagorean Theorem search it up so you can use it to find the missing value for number 4.

Answer 1

Answers:

Question 4

Since line KL shows the amount of unwanted material from line NM, subtract the two and divide the result by 2 for the bottom measurement to each triangle

36 - 20 = 16

16/2 = 8

So now since we know our a and our c, we can implement the Pythagorean theorem of a^2 + b^2 = c^2 to find b, or the height of the triangle

8^2 + b^2 = 17^2

64 + b^2 = 289

b^2 = 225

b = 15

Therefore x = 15ft

Question 5

An outline for the word problem can look like this:

/ | \

/ | \

/ | \

/ | \ 450m

/ | \

/ 360m | \

/ | \

/__________|__________\

x

So to start we already know 2 of the 3 angles for the Pythagorean theorem so now we plug them in

360^2 + a^2 = 450^2

129600 + a^2 = 202500

a^2 = 72900

a = 270

So this means that the wires need to be grounded 270m away from the pole
