can anyone solve this question
plz anyone solve urgent.
Answers
Step-by-step explanation:
a. In ∆ABC
angle A +angle B +angle C = 180°(angle sum property)
5x+3x+2x= 180°
10x=180°
x=180°/10
x=18°
angle A= 90°
angle B= 54°
angle C= 36°
b. In∆PQR
angle P+angle Q+angle R= 180°
x+x+x= 180°
3x= 180°
x= 180°/3
x= 60°
angle P=R=Q=60°
c. In∆NLM
angle N+angle L+angle M= 180°
x-10°+30°+x+10°=180°
2x+30°=180°
2x=150°
x=75°
N=65
M= 85
d. Angle P+Q+R= 180°
90°+ 2x+ 3x= 180°
5x= 180°-90°
x= 18°
Q=36
R=54
Answer:
(a)the angles ∠°,∠°,∠°
(b) ∠∠∠°
(c) ∠°,∠°,∠°
(d)∠°,∠°,∠°
Step-by-step explanation:
Total of all angles in a triangle is °,. so
(a)
, thus the angles
degrees respectively.
(b)
thus each angle is °.
(c)
thus the angles are °,°,°.
(d)
hence each angle is °,°,°
Hence the answers
