45,45 and 90
because 2 of the sides are the same and one is bigger than the other 2
Answer:
15 cm
Step-by-step explanation:
Use the definition of the area of a square:
Where s is the side of the square.
Replace the known value in:
Answer:
x = 4
Step-by-step explanation:
6x + 3 = 2x + 19 ------ subtract 3 both sides
6x + 3 - 3 = 2x + 19 - 3 simplify
6x = 2x + 16 ------ subtract 2x both sides
6x - 2x = 2x + 16 - 2x simplify
4x = 16
x = 16 / 4
x = 4
Answer:
1/(x+6)
Step-by-step explanation:
I'm assuming you want me to factorize
x^2+4x-12 would factorize into (x-2) and (x+6)
Therefore, the numerator (x-2) would cancel with the part of the numerator (x-2) leaving 1/(x+6)
Answer:
For , we expect . Then recalling that , we have
Then by definition of tangent,
Step-by-step explanation:
