Answer:
51°,51°,78°
Step-by-step explanation:
The sum of angles in a triangle add up to 180°
Let x,y be two different numbers
suppose x^2=y^2
then x^2-y^2=0
which yields (x+y)(x-y)=0
so either x=y or x=-y
In any case, x and y must be the same value
also when a vairable is squared like y=x^2
we must note that there are 2 possible solutions
x=(+/-)sqrt(y)
Answer:
F = ( 9/5) X c + 32
Step-by-step explanation:
Answer: x=9
Step-by-step explanation:
