Answer: 4/3
Step-by-step explanation: 4 / 3 = 4/3
Answer:
angle B is 38 degree
Step-by-step explanation:
In triangle ADC,
finding angle C
angle A + angle C = 110 degree (sum of two interior opposite angles are equal to the exterior angle formed)
46 + angle C = 110
angle C = 110 - 46
angle C = 64 degree
In triangle ABC
finding angle B
angle A + angle B + angle C = 180 degree (sum of interior angles of a triangle)
78 + angle B + 64 = 180
142 + angle B = 180
angle B = 180 - 142
angle B = 38 degree
Answer:the correct answer is b
Step-by-step explanation:
Answer:
x= 120°
Step-by-step explanation:
By first method-
exterior angle= sum of two opposite interior angle
x= 60°+60°
x = 120°
By second method-
sum of interior angles of triangle is= 180°
Let one interior angle be y
then
60°+60° +y = 180°
120°+y= 180°
y= 180°-120°
y= 60°
Now
x+y = 180°[ linear pair]
x+ 60°=180°[y=60°]
x= 180°-60°
x=120°
