Step-by-step explanation:
Solve the rational equation by combining expressions and isolating the variable x
Answer:
tan theta = 2 sqrt(5) /15
Step-by-step explanation:
sin theta = opp / hypotenuse
sin theta = 2/7
We can use the Pythagorean theorem to find the length of the adjacent side
a^2 + b^2 = c^2
2^2 +adj^2 = 7^2
4 + adj^2 = 49
adj ^2 = 49-4
adj^2 = 45
Taking the square root of each side
adj = sqrt(45) = sqrt(9*5) =sqrt(9) sqrt(5) = 3 sqrt(5)
The tan theta = opp/ adj
tan theta = 2 / 3 sqrt(5)
Multiply by sqrt(5) / sqrt(5)
= 2 sqrt(5) / 3 *5
= 2 sqrt(5) /15
Taking 30% percent of something is the same as multiplying by .3
so, .3*20 = 6
Answer:
Length x Width
Step-by-step explanation:
Answer:
Step-by-step explanation:
Solve the quadratic equation by factorizasion
- x² + x - 6 = 0
- x² - 2x + 3x - 6 = 0
- x(x - 2) + 3(x - 2) = 0
- (x + 3)(x - 2) = 0
- x + 3 = 0 or x - 2 = 0
- x = - 3 or x = 2
