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:
∪ means the whole numbers which is found in them
B and C have the numbers, 3,7, 6, 9, 2, 5
so, B∪C={2, 3, 5, 6, 7, 9)

Answer:
1 
centimeters
Step-by-step explanation:
The diameter is equal to the radius × 2. We know that the radius is equal to 3/5 centimeters.
To solve this you must do 
× 2.
This equals 
, or 1 cm.
Answer:
1
Step-by-step explanation:
4(4-w) = 3(2w+2)
Use distributive property:
16 - 4w = 6w + 6
+4w +4w
------------------------
16 = 10w + 6
-6 -6
-------------------------
10 = 10w
---- -----
10 10
1 = w
