Answer:
Cos A = x/z
Step-by-step explanation:
You need to memorize the definitions of all the trig functions and then these types of problems become easy! OK?
Cos = adjacent side/hypotenuse
Cos A = x/z
The answer is -0.382683432 if 112.5 is in degrees
The quadratic formula helps us solve any quadratic equation. First, we bring the equation to form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) . See examples of using the formula to solve a variety of equations.
This is proven and I’m positive this is what your asking! BRAINLIEST please
P=4*a, where P - perimeter, a - length of one side of the square.
if a=x+3 and P=48, then 4(x+3)=48;
x=9.
Answer: 9 units.
Answer:
S = (1 times 5)times 6
