Step-by-step explanation:
angle A = 40
angle B = 60
angle C = we don't know.
A + B + C = 180
C = 180 - A - B
C = 180 - 40 - 60
C = 80
40 + 60 + 80 = 180
180 = 180...It checks!
Answer:
(a) = 0.32 or 8/25
(b) = 0.48 or 12/25
(c) = 4 Boards
Step-by-step explanation:
(a):
0.8 x 2/5
8/10 x 4/10
(8 x 4) / (10 x 10)
(32) / (100)
0.32 or 8/25
(b):
0.8 x 3/5
8/10 x 6/10
(8 x 6) / (10 x 10)
(48) / (100)
0.48 or 12/25
(c):
0.8 x 5
8/10 x 50/10
(8 x 50) / (10 x 10)
(400) / (100)
4 Boards
The answer is 45. Because if you do 15 times 3 it would give you 45. So answer is 45cm
