@SpartanRace

OpenStudy (anonymous):

Divide 30 by 24

OpenStudy (anonymous):

What do yo get?

OpenStudy (anonymous):

1.25

OpenStudy (anonymous):

Now what is 1.25 times 10

OpenStudy (anonymous):

12.5

OpenStudy (anonymous):

Tada you have x

OpenStudy (anonymous):

next one @theslasher00

OpenStudy (anonymous):

Or so I think, I am half awake typing with one hand so, yeah

Refer to the diagram below. Surveyors know that ΔPQR and ΔSTR are similar. What is PQ, the distance across the lake?

OpenStudy (anonymous):

It is similar

OpenStudy (anonymous):

can u wal me thro it please

OpenStudy (anonymous):

What's 2.25/1.25?

OpenStudy (anonymous):

1.8

OpenStudy (anonymous):

Now, what is 1.8 X 1.8

OpenStudy (anonymous):

3.24

OpenStudy (anonymous):

Now that should be the distance accross the lake brb

A 6-ft adult has a shadow 3.6 ft long. How long is the shadow of a 5-ft child standing next to the adult?

OpenStudy (anonymous):

Do you understand the last two?

OpenStudy (anonymous):

some what still need help

OpenStudy (anonymous):

Ok so because 1.25 times 1.8 = the 2.25 of the other side on the other triangle , 1.8 times the base of the first triangle 1.8 = the base side of the other triangle

OpenStudy (anonymous):

Sorry I suck at explaining stuff

OpenStudy (anonymous):

how u find it is it like the other two

OpenStudy (anonymous):

Ok if you don't have it in sight yet , open up the link for the triangles in a second tab

OpenStudy (anonymous):

Triangle RST is congruent to PQR

OpenStudy (anonymous):

Like, triangle PQR is jsut a bigger version

OpenStudy (anonymous):

So because if you look at it, The side 1.25 is the same side as the 2.25 on the other triangle

OpenStudy (anonymous):

The purpose of this question is to find PQ and to do so you must figure out how much bigger the second triangle is

OpenStudy (anonymous):

To figure this out you can divide 2.25 by 1.25 to see what number was used to get the bigger triangle which ends up being 1.8
