Question

plzz answer these correctly answer these all if u cant understand my handwriting u can ask me the question in comments

Answer 1

2 the anwer is 90°, 45°, 45°

Answer 2

hey mate !!❤✌
here's ur answer ✍✍✍

➡️ 1 km = 1000m
1hectare = 10000m^2

➡️ let the angles be 3x, 4x &5x
as we know
sun of all angles of a ∆ is 180°
≈> 3x + 4x+5x = 180°
12x = 180°
x=15
ANGLES = 3×15 =45°
= 4×15 = 60°
=5×15=75°

➡️ In right angle ∆ one angle = 90°
and other angles are given in ratio of 4:5
let the angles be 4x and 5x
4x + 5x + 90 =180° { angle sum property of triangle}
9x =90°
x = 10
4x = 40°
5x = 50°

➡️ Angle 1=70°
Angle 2=angle 3 ( angles opp. to equal sides)
other two angles be x
2x+70°=180°
2x=110°
x=55°
