ok

- calculusxy

Now do you understand on how to figure this out?

- anonymous

ok

- ranga

Find the third angle first. Whichever angle is the biggest the side opposite to that will be the longest.

- anonymous

angle A and C is the longest side

- ranga

Angle C = 80 > Angle A = 60 > Angle B = 40
Therefore, side c > side a > side b

- anonymous

ok thank

- ranga

you are welcome.

two sides of an isosceles triangle measure 3 and 7. which of the following could be the measure of the third side?

- nikato

so u know an isoscels trianlge must ahve 2 sides that are congrunet. since u have a side that is 3 and another 7. the 3rd side must be either 3 or7

- anonymous

yea

- nikato

yea, thats it

- anonymous

the answer is [1] 9 [2] 7 [3] 5 [4] 3

- nikato

well, it could be either 2 or 4 with all the info u were given

- anonymous

ok thanks

- anonymous

in triangle ABC, m<=48, and m

- nikato

|dw:1388369988615:dw|can u find

**
**

- anonymous

ADD 48 AND 24
AND IT GIVE YOU 72

- anonymous

IS IT RIGHT

- nikato

yes, then subtract that from 180. then tell me if that is obtuse or actue

- anonymous

obtuse

- nikato

correct, taht measn triangle ABC is obtuse

- anonymous

in the accompanying diagram, BA=BC and m\[\forall

- nikato

waht diagram

- anonymous

|dw:1388374843523:dw|

- nikato

|dw:1388375062951:dw|so this is what you have. what are u solving for?

- anonymous

for Y

- nikato

|dw:1388375208766:dw|can u solve for that angle if a line=180

- anonymous

180-117=63

- nikato

|dw:1388375443532:dw| y=63 becuz the base angles of an isoscles trinagle are congruent and by vertical angle thoerem thsoe 2 angles are also congruent

- anonymous

thank you

- nikato

your welcome

- nikato

they must be less than 90

- anonymous

thanks

- anonymous

given: AB=DE and < A=

- nikato

|dw:1388376739438:dw|so this is whats given. and can u show me ur choices

- anonymous

[1] SAS [2] ASA [3] SSS [4] there is insufficient information to Determine if the triangles are congruent

- nikato

if this is allt eh info even, then i think is 4

at a certain time of the day the shadow of a 5' boy is 8' long. the shadow of a nearby flagpole at this same time is 28 long. how tall is the flagpole?

- nikato

set up a propertion and solve

- nikato

|dw:1388377765971:dw|

- anonymous

I got 17.5

- nikato

ok, then that should be the height of the actual flagpole

- anonymous

thank

- anonymous

Given: AD is congruent to CD, AB=CB
prove: angle ABD=angle CBD|dw:1389560316762:dw|

- nikato

Use SSS becuz BD=BD by reflexive
