Assuming cos means cos(x);
Combine all like terms: cos(x)(√2 - 12)= -1
Isolate x: cos(x)= -1/(√2 - 12)
cos(x)=0.0944
x=cos⁻¹(0.0944)
x= 84.57 degrees or (360-x=275.42 degrees)
Hope I helped :)
70 - 42 = ______. GO i know you can do it!!
The answer to the question
To graph a linear equation, you use y=mx+b. To graph a quadratic equation you use y=ax^2 + bx + c. You cannot use the same strategy to graph a quadratic equation, as in order to graph a quadratic equation, you would execute it differently. The idea is the same however, to plug numbers into the equation to find your coordinates.
