What is the approximate percent decrease when a fish count goes down from 850 to 500?

8 0

To get this, you divide the smaller number by the larger one and get 0.5882... 500 is about 59% of 850, so to find the percent lost, you subtract that from 100 to get 41% decrease

ST = 23
RU = 8
SV = 5
SU = 10

====================================================

Explanation:

Focus on triangles SVT and UVT.

They are congruent triangles due to the fact that SV = VU and VT = VT. From there we can use the LL (leg leg) theorem for right triangles to prove them congruent.

Since the triangles are the same, just mirrored, this means ST = UT = 23.

-----------------------

Following similar reasoning as the previous section, we can prove triangle RVU = triangle RVS.

Therefore, RS = RU = 8

-----------------------

SV = VU = 5 because RT bisects SU.

Bisect means to cut in half. The two smaller pieces are equal.

-----------------------

SU = SV + VU = 5+5 = 10

Refer to the segment addition postulate.
