I think you can use cosine rule if only the lines that form the <52 are equal.
Answer:
B
Step-by-step explanation:
Since equalateral all angles are 60. 60 - 69 = -9.
Answer:
A. 2
Step-by-step explanation:
Answer:
P(A n B) = 5
Step-by-step explanation:
From the venn diagram given, we can see that;
P(A) = 25
P(B) = 15
P(A n B) = 5
Thus,the correct answer of P(A n B) which is the intersection between A and B is 5
First of all you need to get rid of the -27 on the left side, to do so you add 27 to both sides so it becomes:
5/8a=20
Now you can divide it by 5 to get:
1/8a=4
Now multiply it by 8 to get:
a=32
Hope this helps :)
