Question

PLEASE HELP ASAP!! HELP ASAP!!

Answer 1

{by angle sum property of triangle}
\_S+\_T+\_U=180°
65°+\_T+70° =180°
\_T=180°-135°
\_STU = 45°

Shortest angle=\_STU=45°
=>Shortest side=SU
{side opp to smaller angle is smaller}

SIMILARLY.....

Greatest angle=\_TUS=70°
=>Greatest side=TS
{side opp to greater angle is greater}

So, the correct order is...
SU<UT<ST
last option

Answer 2

angle T is 180 degree - (70+65)

= 180 -135

= 45 degree.

we know that the measures of angle in triangle is directly proportional to length of side of triangle.

smallest angle is angle T = 45 degree.
hence
__
SU is shortest side.

similarly,
__
UT is bigger than
__
SU.
__
ST is longest side.

hence , order of side from shortest to longest :-
__ __ __
SU<UT<ST .
