Angle C=180-(39+28)=180-67=113.
Sine rule:
c/sinC=a/sinA, c=asinC/sinA=23.40 approx.
Answer:
2x i hope it is right good luck
8 pigs x 4 legs each = 32. so you need 2 ducks to give you 10 animals total. So 32 + 2 ducks with 2 legs = 36.
There are 8 pigs and 2 ducks.
we are given
(5.2 − 4.5) − 5.5 + 4.8
we will check each steps
we always use PEMDAS rule
P: Parenthesis
E: Exponent
M: Multiplication
D: Division
A: Addition
S: Subtraction
Step 1: (5.2 − 4.5) − 5.5 + 4.8
This is same as original
so, this is TRUE
Step 2: 5.2 + (− 4.5 − 5.5) + 4.8 (identity property)
we know that
identity property is
0+a=a
so, this is FALSE
Step 3: 5.2 − 10 + 4.8
this is TRUE
Step 4: 5.2 + 4.8 − 10 (commutative property)
we know that commutative property is
a+b=b+a
so, this is TRUE
Step 5:
10 − 10 = 0
this is TRUE
