Step-by-step explanation:
(2). let suppose that the two equal angles of ∆ are x
x+x+80°=180°( angle sum property)
2x=180°-80°=100°
x=100°/2=50°
x=50°
(3). (i) 45°+30°+x=180°
75°+x=180°
x=180°-75°=105°
(ii) X+90°+30°=180°
x+120°=180°
X+180°-120°=60°
(iii)60°+65°+y=180°
125°+y=180°
y=180°-125°=55°
y+x= 180°
55°+x=180°
x=180°-55°=125°
koi nhi
guys do 1 please
please
I give brainlyest
plz do part 1 by 6pm please
if the ratio of angles are 2:3:4 then we let that angles will be 2x ,3x,4x
now on applying Angel sum property then 2x+3x+4x=180°
9x=180° then x=180°/9 and then x=20°
now 2x=2×20°=40°; 3x=3×20°=60°; 4x=4×20°=80°
thanks
