Answer:
x=6
Step-by-step explanation:
I would look at this triangle and notice that x can be solved by setting up a ratio.
I generally put the short side of the triangle on the top and the long side on the bottom
4/x = x/9
You then cross multiply to get 36=x^2, or +-6=x
A length of a triangle cannot be negative, so we are left with the answer x=6
The answer is H to your question
5x^2+4x-2 This is a second degree polynomial since the largest exponent is x^2
Answer:
76°
Step-by-step explanation:
by definition, supplementary angles sum up to 180°
hence,
104° + supplementary angle = 180°
supplementary angle = 180° - 104°= 76°
