Answer: 54
Step-by-step explanation: 30, percentage increased by 80% (percent) of its value = 54
I can't conveniently copy the logical symbols you use, so I write
AND = ∧ (conjunction)
OR = ∨ (disjunction)
NOT = ¬
Tautologically,
p = (p AND q) OR (p AND NOT q)
and we can distribute the OR to get the equivalent statement
(p OR (p AND NOT q)) AND (q OR (p AND NOT q))
and again to get
((p OR p) AND (p OR NOT q)) AND ((p OR q) AND (q OR NOT q))
Now, q OR NOT q is always true, and p OR p is simply p, so we have
p = p AND (p OR q) AND (p OR NOT q)
This shows that p OR NOT q is already included in p, so our initial statement is simply
p AND (NOT p OR NOT q)
Distributing the conjunction, we get
(p AND NOT p) OR (p AND NOT q)
p AND NOT p is tautologically false, but we're considering a disjunction, so the truth value of p AND NOT q is the only value that's relevant. So, the initial statement collapses to
p AND NOT q
The value of x is 2x+38=90
The answer is x=26
In figure,
AC = BC (given)
Since, in a triangle , angles opposite to equal sides are also equal.
Therefore,
b= 52°
Now,
°.° c is exterior angle of triangle.
.°. c = b + 52°
=> c = 52° + 52°
=> c = 104°
Solution:-
-------------
b = 52° & c =104°
