Answer 4

find the size of angle C

use angle sum of a triangle..

then use the rule

the longest side in a triangle is opposite the largest angle..

the shortest side is opposite the smallest angle...

middle length opposite the middle sized angle..

hope it helps

Answer 5

for question 2

the sum of the 2 shorter sides must be greater than the measure of the longest side.

Answer 6

I am confussed :( sorry I am not good at this

Answer 7

Q1 ans CB is the largest side then comes AC and AB is the smallest

the side opposite to the largest angle is the largest side. you can find angle C bu using the angle sum property!

angleA + angleB + angleC = 180 degrees
75 + 58 + angleC = 180
angle C= 180-133 = 47 degrees!!

good luck!!

Answer 8

that is option C AB,AC,BC
