Here, You need to understand "The Linear Pair" equation, it tells, one straight line gives 180 degrees of angle (number of different angle doesn't matter)
Now, by applying this, we can get all the angles of that Pentagon:
180 - 60 = 120
180 - 70 = 110
180 - 65 = 115
180 - 40 = 140
180 - y = 180 - y
Now, Sum of all the angles would be 540,
120 + 110 + 115 + 140 + 180 - y = 540
665 - y = 540
y = 665 - 540
y = 125
In short, Your Final Answer would be 125
Hope this helps!
Answer:
0.11
Step-by-step explanation:
your answer would be 0.11 I think.
Answer:
34
Step-by-step explanation:
a + b = c
a = 5
b = 12
12 + 5 = 17, 17 + 17 = 34 :D
It would be 2. have a great day
She mixed up the commutative and associative properties
Line 3 should be commutative and line 4 should be associative.
Line 3 is commutative because she swapped -3.4 and 8.2
Line 4 is associative because of the parenthesis groupings.
Other than that I don't see any other errors.
