Answer:
92°
Step-by-step explanation:
By exterior angle theorem:

Answer:
9.73 cm to 2 DP
Step-by-step explanation:
Total of the lengths involved = 7*9.4 + 5*10.2
= 116.8 cm
So the mean of the 12 fingers
= 116.8/12
= 9.73 cm to 2 DP.
56% can be represented with 56/100. That fraction can be reduced (or simplified) to 14/25.
8(4) + 4(4) + 4(2)
32 + 16 + 8
^^ Either one of these two expressions can be written down and they'd both be right.
