The sum of all three angles will always be 180 degrees.
Answer:
if ∠Q=∠R
draw an angular bisector from P to QR in which it intersect wit Qr at point S
now we have two triangle : QPS and RSP
in which angle : QPS=RPS ( PS is angular bisector)
and we have angle Q and angle R are equal
and PS is common side
this makes triangle QPS and RSP are congruent by AAS(angle angle side)
which also means that pQ=PR ( proved)
<span>angles of abc in order from smallest to largest.
<ABC, <CAB, <ACB
Hope it helps
p.s.
smallest angle opposites shortest side
largest angle opposites longest side</span>
First one = 9x3=27
Second one 12x9=108
3rd one = 3x4=12
Idk what that last one is
7/5 x 7/1 = 49/5 or 9 4/5
